POU2AF1
POU domain class 2-associating factor 1 is a protein that in humans is encoded by the ''POU2AF1'' gene. The protein is also termed Oct coactivator from B cells (i.e. OCAB), Oct binding factor 1 (OBF1 or OBF-1), and, as commonly found in the literature, BOB1.https://www.ncbi.nlm.nih.gov/gene?term=(ocab ene%20AND%20(Homo%20sapiens rgn%20AND%20alive rop20NOT%20newentry enesort=weight BOB1 is a transcriptional coactivator (i.e. a protein that controls the activity of transcription factors) which is expressed principally by B-cell lymphocytes and controls immunoglobulin and other genes critical for these cells expression of CD20, CRISP-3, and CD36. The expression of BOB1 has proven useful for identifying certain lymphomas as being B-cell lymphomas, as exemplified in studies which use BAB1 expression to help identify lymphomas as being diffuse large B-cell lymphomas, not otherwise specified.

SIAH1
E3 ubiquitin-protein ligase SIAH1 is an enzyme that in humans is encoded by the ''SIAH1'' gene. Function This gene encodes for a polypeptide structure that is a member of the seven in absentia homolog (SIAH) family. The protein is an E3 ligase and is involved in ubiquitination and proteasome-mediated degradation of specific proteins. The activity of this ubiquitin ligase has been implicated in the development of certain forms of Parkinson's disease, the regulation of the cellular response to hypoxia and induction of apoptosis. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. Interactions SIAH1 has been shown to interact with: * APC, * BAG1, * CACYBP, * KHDRBS3, * KIF22, * NUMB, * PEG10, * PEG3 * POU2AF1, * RBBP8 Retinoblastoma-binding protein 8 is a protein that in humans is encoded by the ''RBBP8'' gene.

Diffuse Large B-cell Lymphoma
Diffuse large B-cell lymphoma (DLBCL) is a cancer of B cells, a type of lymphocyte that is responsible for producing antibodies. It is the most common form of non-Hodgkin lymphoma among adults, with an annual incidence of 7–8 cases per 100,000 people per year in the US and UK. This cancer occurs primarily in older individuals, with a median age of diagnosis at ~70 years, although it can occur in young adults and, in rare cases, children. DLBCL can arise in virtually any part of the body and, depending on various factors, is often a very aggressive malignancy. The first sign of this illness is typically the observation of a rapidly growing mass or tissue infiltration that is sometimes associated with systemic B symptoms, e.g. fever, weight loss, and night sweats. The causes of diffuse large B-cell lymphoma are not well understood. Usually DLBCL arises from normal B cells, but it can also represent a malignant transformation of other types of lymphoma (particularly marginal zone ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid resid ...

CD36
CD36 (cluster of differentiation 36), also known as platelet glycoprotein 4, fatty acid translocase (FAT), scavenger receptor class B member 3 (SCARB3), and glycoproteins 88 (GP88), IIIb (GPIIIB), or IV (GPIV) is a protein that in humans is encoded by the CD36 gene. The CD36 antigen is an integral membrane protein found on the surface of many cell types in vertebrate animals. It imports fatty acids inside cells and is a member of the class B scavenger receptor family of cell surface proteins. CD36 binds many ligands including collagen, thrombospondin, erythrocytes parasitized with ''Plasmodium falciparum'', oxidized low density lipoprotein, native lipoproteins, oxidized phospholipids, and long-chain fatty acids. Work in genetically modified rodents suggest a role for CD36 in fatty acid metabolism,heart disease, taste, and dietary fat processing in the intestine. It may be involved in glucose intolerance, atherosclerosis, arterial hypertension, diabetes, cardiomyopathy, Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POU Domain
POU (pronounced 'pow') is a family of proteins that have well-conserved homeodomains. Etymology The acronym POU is derived from the names of three transcription factors: * the Pituitary-specific Pit-1 * the Octamer transcription factor proteins Oct-1 and Oct-2 (octamer sequence is ATGCAAAT) * the neural Unc-86 transcription factor from ''Caenorhabditis elegans''. Diversity POU domain genes have been described in organisms as divergent as ''Caenorhabditis elegans'', ''Drosophila'', ''Xenopus'', zebrafish and human but have not been yet identified in plants and fungi. Comparisons of POU domain genes across the animals suggests that the family can be divided into six major classes (POU1-POU6). Pit-1 is part of the POU1 class, Oct-1 and Oct-2 are members of POU2, while Unc-86 is a member of POU4. The six classes diverged early in animal evolution: POU1, POU3, POU4, and POU6 classes evolved before the last common ancestor of sponges and eumetazoans, POU2 evolved in the ...

Lymphoma
Lymphoma is a group of blood and lymph tumors that develop from lymphocytes (a type of white blood cell). In current usage the name usually refers to just the cancerous versions rather than all such tumours. Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired. The enlarged lymph nodes are usually painless. The sweats are most common at night. Many subtypes of lymphomas are known. The two main categories of lymphomas are the non-Hodgkin lymphoma (NHL) (90% of cases) and Hodgkin lymphoma (HL) (10%). The World Health Organization (WHO) includes two other categories as types of lymphoma – multiple myeloma and immunoproliferative diseases. Lymphomas and leukemias are a part of the broader group of tumors of the hematopoietic and lymphoid tissues. Risk factors for Hodgkin lymphoma include infection with Epstein–Barr virus and a history of the disease in the family. Risk factors f ...

Gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as g ...

CD20
B-lymphocyte antigen CD20 or CD20 is expressed on the surface of all B-cells beginning at the pro-B phase (CD45R+, CD117+) and progressively increasing in concentration until maturity. In humans CD20 is encoded by the ''MS4A1'' gene. This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule that plays a role in the development and differentiation of B-cells into plasma cells. This family member is localized to 11q12, among a cluster of family members. Alternative splicing of this gene results in two transcript variants that encode the same protein. Function The protein has no known natural ligand and its function is to enable optimal B-cell immune response, specifically against T-independent antigens. I ...

Immunoglobulin
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can ''tag'' a microbe or an infected cell for attack by other parts of the immune system, or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion). To allow the immune system to recognize millions of different antigens, the antigen-binding sites at both tips of the antibody come in an equally wide variety. In contrast, the remainder of the antibody is relatively constant. It only occurs in a few varian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
