RBX1
RING-box protein 1 is a protein that in humans is encoded by the ''RBX1'' gene. Function This gene encodes an evolutionarily conserved protein that interacts with cullins. The protein plays a unique role in the ubiquitination reaction by heterodimerizing with cullin-1 to catalyze ubiquitin polymerization. It also may be involved in the regulation of protein turn-over. Interactions RBX1 has been shown to interact with: * CAND1, * CUL1, * CUL2, * CUL4A, * CUL5 * CUL7, * DCUN1D1, and * P70-S6 Kinase 1 Ribosomal protein S6 kinase beta-1 (S6K1), also known as p70S6 kinase (p70S6K, p70-S6K), is an enzyme (specifically, a protein kinase) that in humans is encoded by the ''RPS6KB1'' gene.

CUL4A
Cullin-4A is a protein that in humans is encoded by the ''CUL4A'' gene. CUL4A belongs to the cullin family of ubiquitin ligase proteins and is highly homologous to the CUL4B protein. CUL4A regulates numerous key processes such as DNA repair, chromatin remodeling, spermatogenesis, haematopoiesis and the mitotic cell cycle. As a result, CUL4A has been implicated in several cancers and the pathogenesis of certain viruses including HIV. A component of a CUL4A complex, Cereblon, was discovered to be a major target of the teratogenic agent thalidomide. Structure CUL4A protein is 759 amino acids long and forms an extended, rigid structure primarily consisting of alpha-helices. At the N-terminus, CUL4A binds to the beta-propeller of the DDB1 adaptor protein which interacts with numerous DDB1-CUL4-Associated Factors (DCAFs). As a result, the N-terminus is crucial for the recruitment of substrates for the ubiquitin ligase complex. At the C-terminal end, CUL4A interacts with the RBX1/RO ...

CUL5
Cullin-5 is a protein that in humans is encoded by the ''CUL5'' gene. Discovery The mammalian gene product was originally discovered by expression cloning, due to the protein's ability to mobilize intracellular calcium in response to the peptide hormone arginine vasopressin. It was first titled VACM-1, for vasopressin-activated, calcium-mobilizing receptor. Since then, VACM-1 has been shown to be homologous to the Cullin family of proteins, and was subsequently dubbed cul5. Tissue distribution Studies have shown that the cul5 protein is expressed at its highest levels in heart and skeletal tissue, and is specifically expressed in vascular endothelium and renal collecting tubules. Function Cul5 inhibits cellular proliferation, potentially through its involvement in the SOCS/ BC-box/ eloBC/ cul5/ RING E3 ligase complex, which functions as part of the ubiquitin system for protein degradation. One study have shown that Cul5 plays a role in Reelin signaling cascade, participating in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 residue ...

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 gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cullin
Cullins are a family of hydrophobic scaffold proteins which provide support for ubiquitin ligases (E3). All eukaryotes appear to have cullins. They combine with RING proteins to form ''Cullin-RING ubiquitin ligases'' (CRLs) that are highly diverse and play a role in myriad cellular processes, most notably protein degradation by ubiquitination. The human genome contains eight cullin genes * CUL1, part of SCF complex * CUL2, part of ECS complex (Elongin C - CUL2 - SOCS-box) * CUL3, part of CUL3-BTB complex * CUL4A * CUL4B * CUL5 * CUL7 * CUL9, also known as PARC There is also a more distant member called ANAPC2 (or APC2), part of the Anaphase-promoting complex. CUL1, 2, 3, 4A, 4B, 5 and 7 each form part of a multi-subunit ubiquitin complex. Cullin-RING ubiquitin ligases Cullin-RING ubiquitin ligases (CRLs), such as Cul1 (SCF) play an essential role in targeting proteins for ubiquitin-mediated destruction; as such, they are diverse in terms of composition and function, regu ...
