polypeptide Polypeptid
Pancreatic Polypeptide definition: A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.
Cystatin C definition: An extracellular cystatin subtype that is abundantly expressed in bodily fluids. It may play a role in the inhibition of interstitial CYSTEINE PROTEASES.
Tissue Polypeptide Antigen definition: Serological tumor marker composed of a molecular complex of cytokeratins 8, 18, and 19. It is used in the diagnosis and staging of bronchogenic carcinoma.
Inhibin-beta Subunits definition: They are glycopeptides and subunits in INHIBINS and ACTIVINS. Inhibins and activins belong to the transforming growth factor beta superfamily.
Chorionic Gonadotropin, beta Subunit, Human definition: The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.
Human Chorionic Gonadotropin Beta Subunit definition: Contiguous with the LH beta subunit gene on chromosome 19q13.3, six homologous genes arranged in tandem and inverted pairs encode the beta subunit of Chorionic Gonadotropin (Glycoprotein Hormone Beta Family).Glycoprotein hormones are heterodimers of a common alpha subunit and a unique beta subunit that confers biological specificity. Produced by placental trophoblasts, Chorionic Gonadotropin stimulates ovarian steroid synthesis essential for maintenance of pregnancy. (NCI)
Human Chorionic Gonadotropin Beta Subunit definition: Human chorionic gonadotropin is a glycoprotein hormone produced by placental trophoblasts 10-12 days after conception and during the first trimester. HCG binds to the corpus luteum to stimulate progesterone production, which maintains the secretory endometrium and the fetus. HCG is a heterodimer of a common alpha chain and a unique beta chain that confers biological specificity to thyrotropin, lutropin, follitropin and gonadotropin. (from OMIM 118860, SWISS-PROT P01233, and NCI)
CD3E Antigen Epsilon Polypeptide definition: The CD3 complex mediates signal transduction. The TCR/CD3 complex of T lymphocytes consists of either a TCR Alpha/Beta or TCR Gamma/Delta heterodimer coexpressed at the cell surface with the invariant subunits of CD3 labeled Gamma, Delta, Epsilon, Zeta, and Eta. CD3E Antigen, Epsilon Polypeptide (Tit3 Complex) is encoded by the CD3E gene. Recruitment of Nck by CD3 epsilon reveals a ligand-induced conformational change essential for T cell receptor signaling and synapse formation. (From LocusLink, Swiss-Prot and NCI)
Collagen I (Alpha 1) definition: Collagen I (Alpha 1), encoded by the COL1A1 gene, is the major component of type I collagen, the fibrillar collagen found in most connective tissues, and the only component of the collagen found in cartilage. Mutations in this gene are associated with osteogenesis imperfecta, Ehlers-Danlos syndrome, and idiopathic osteoporosis. Reciprocal translocations between chromosomes 17 and 22, where this gene and the gene for platelet-derived growth factor beta are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans, resulting from unregulated expression of the growth factor. Two transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene. (from LocusLink)
positive regulation of antibacterial peptide biosynthetic process definition: Any process that activates or increases the frequency, rate, or extent of antibacterial peptide biosynthesis. [GOC:mah, PMID:10973475]
