Spermadhesin
CUB domain is an evolutionarily conserved protein domain. The CUB domain (for complement C1r/C1s, Uegf, Bmp1) is a structural motif of approximately 110 residues found almost exclusively in extracellular and plasma membrane-associated proteins, many of which are developmentally regulated. These proteins are involved in a diverse range of functions, including complement activation, developmental patterning, tissue repair, axon guidance and angiogenesis, cell signalling, fertilisation, haemostasis, inflammation, neurotransmission, receptor-mediated endocytosis, and tumour suppression. Many CUB-containing proteins are peptidases belonging to MEROPS peptidase families M12A (astacin) and S1A (chymotrypsin). Examples Proteins containing a CUB domain include: * Mammalian complement subcomponents C1s/C1r, which form the calcium-dependent complex C1, the first component of the classical pathway of the complement system. * ''Cricetidae sp.'' (Hamster) serine protease Casp, which d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seminal Fluid
Semen, also known as seminal fluid, is an organic bodily fluid created to contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the female ovum. Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen from the urethral orifice is called ejaculation. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". The fluid is designed to be discharged deep into the vagina, so the spermatozoa can pass into the uterus and form a zygote with an egg. Semen is also a form of genetic material. In animals, semen has been collected for cryoconservation. Cryoconservation of animal genetic resources is a practice that call ...

Protein Domain
In molecular biology, a protein domain is a region of a protein's polypeptide chain that is self-stabilizing and that folds independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains, and a domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions. In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length. The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium-binding EF hand domain of calmodulin. Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins. Background The concept of the domain was first proposed in 1973 by Wetlaufer aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSMD1
CSMD1 CUB and Sushi multiple domains 1 is a protein that in humans is encoded by the ''CSMD1'' gene. Structure CSMD1 contains 14 N-terminal CUB domains that are separated from each other by a Sushi domains followed by an additional 15 tandem Sushi domain segment. Function Based on analogy to other proteins that contain Sushi domains, it is believed that the gene product of CSMD1 functions as a Complement control protein. Clinical significance It is a potential tumour suppressor, the deletion of which may result in head and neck carcinomas behaving more aggressively. CSMD1 protein expression was found to be reduced in patients with invasive breast cancer. Functional studies showed that CSMD1 reduction causes cells to transform to a cancer form by increasing their ability to divide, migrate and invade. In a three dimensional model of breast ducts, reduced CSMD1 expression failed breast duct formation. Certain CSMD1 genetic variants have been found to show an association ...

LRP12
Low density lipoprotein receptor-related protein 1 (LRP1), also known as alpha-2-macroglobulin receptor (A2MR), apolipoprotein E receptor (APOER) or cluster of differentiation 91 (CD91), is a protein forming a receptor found in the plasma membrane of cells involved in receptor-mediated endocytosis. In humans, the LRP1 protein is encoded by the ''LRP1'' gene. LRP1 is also a key signalling protein and, thus, involved in various biological processes, such as lipoprotein metabolism and cell motility, and diseases, such as neurodegenerative diseases, atherosclerosis, and cancer. Structure The ''LRP1'' gene encodes a 600 kDa precursor protein that is processed by furin in the trans-Golgi complex, resulting in a 515 kDa alpha-chain and an 85 kDa beta-chain associated noncovalently. As a member of the LDLR family, LRP1 contains cysteine-rich complement-type repeats, EGF (gene) repeats, β-propeller domains, a transmembrane domain, and a cytoplasmic domain. The extracellular domain of LRP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

KREMEN1
Kremen protein 1 is a protein that in humans is encoded by the ''KREMEN1'' gene. ''Kremen1'' is conserved in chordates including amphioxus and most vertebrate species. The protein is a type I transmembrane receptor of ligands Dickkopf1, Dickkopf2, Dickkopf3, Dickkopf4, EpCAM and Rspondin1. Function This gene encodes a high-affinity dickkopf homolog 1 (DKK1) transmembrane receptor that functionally cooperates with DKK1 to block wingless (WNT)/beta-catenin signaling. The encoded protein is a component of a membrane complex that modulates canonical WNT signaling through lipoprotein receptor-related protein 6 (LRP6). It contains extracellular Kringle Kringle (, ) is a Northern European pastry, a variety of pretzel. Pretzels were introduced by Roman Catholic monks in the 13th century in Denmark, and from there they spread throughout Scandinavia and evolved into several kinds of sweet, salty ..., WSC, and CUB domains.

GPR126
G protein-coupled receptor 126 also known as VIGR and DREG is a protein encoded by the ''ADGRG6'' gene. GPR126 is a member of the adhesion GPCR family. Adhesion GPCRs are characterized by an extended extracellular region often possessing N-terminal protein modules that is linked to a TM7 region via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain. GPR126 is all widely expressed on stromal cells. The N-terminal fragment of GPR126 contains C1r-C1s, Uegf and Bmp1 (CUB), and PTX-like modules. Ligand GPR126 was shown to bind collagen IV and laminin-211 promoting cyclic adenosine monophosphate (cAMP) to mediate myelination. Signaling Upon lipopolysaccharide (LPS) or thrombin stimulation, expression of GPR126 is induced by MAP kinases in endothelial cells. During angiogenesis, GPR126 promotes protein kinase A (PKA)–cAMP-activated signaling in endothelial cells. Forced GPR126 expression in COS-7 cells enhances cAMP levels by coupling to heterotrimeric Gαs/i prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DMBT1
Deleted in malignant brain tumors 1 protein is a protein that in humans is encoded by the ''DMBT1'' gene. Function Loss of sequences from human chromosome 10q has been associated with the progression of human cancers. The gene DMBT1 was originally isolated based on its deletion in a medulloblastoma cell line. DMBT1 is expressed with transcripts of 6.0, 7.5, and 8.0 kb in fetal lung and with one transcript of 8.0 kb in adult lung, although the 7.5 kb transcript has not been characterized. The DMBT1 protein is a glycoprotein containing multiple scavenger receptor cysteine-rich (SRCR) domains separated by SRCR-interspersed domains (SID). Transcript variant 2 (8.0 kb) has been shown to bind surfactant protein D independently of carbohydrate recognition. This indicates that DMBT1 may not be a classical tumor suppressor gene, but rather play a role in the interaction of tumor cells and the immune system. Pattern recognition and potential use of DMBT1 in nanomedicine At epithel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
