| tissue polypeptide antigen | Serological tumour marker composed of a molecular complex of cytokeratins 8, 18, and 19. It is used in the diagnosis and staging of bronchogenic carcinoma. (12 Dec 1998) |
|---|
| tissue-specific antigen | A heterogenetic antigen with organ specificity; e.g., in addition to species-specific antigen, kidney of one species contains antigen that is identical to that in kidney of other species. Synonym: tissue-specific antigen. (05 Mar 2000) |

| basic polypeptide-activated protein kinase | <enzyme> Requires mn2+ for its activity; from bombyx mori; does not require cyclicamp, cyclicgmp or ca Registry number: EC 2.7.1.- Synonym: ba kinase (26 Jun 1999) |
| vasoactive intestinal polypeptide | A polypeptide hormone secreted most commonly by non-beta islet cell tumours of the pancreas, producing copious watery diarrhoea and faecal electrolyte loss, particularly hypokalaemia; VIP increases the rates of glycogenolysis; stimulates pancreatic bicarbonate secretion. Synonym: vasoactive intestinal peptide. (05 Mar 2000) |
| pancreatic polypeptide | <chemical> A 36-amino acid polypeptide with physiological regulatory functions. It is secreted by pancreatic tissue. Plasma pancreatic polypeptide increases after ingestion of food, with age, and in disease states. A lack of pancreatic polypeptide in the islets of langerhans has been associated with the obese syndrome in rats and mice. Chemical name: Pancreatic polypeptide (12 Dec 1998) |
| gastric inhibitory polypeptide | <hormone> Peptide hormone (43 amino acids) that stimulates insulin release and inhibits the release of gastric acid and pepsin. Acronym: GIP (18 Nov 1997) |
| photosystem II D1 polypeptide carboxy-terminal processing protease | <enzyme> From thylakoids; not inhibited by common protease inhibitors Registry number: EC 3.4.99.- Synonym: d1 carboxy-terminal processing protease, d1 c-terminal protease, ctpa gene product (26 Jun 1999) |
| polypeptide | <biochemistry> A peptide which on hydrolysis yields more than two amino acids, called tripeptides, tetrapeptides, etc. According to the number of amino acids contained. (14 Oct 1997) |
| polypeptide fucosyltransferase | <enzyme> From cho cells; attaches fucose through an o-glycosidic linkage to serine or theonine in egf domains Registry number: EC 2.4.1.- Synonym: GDPfucose - polypeptide fucosyltransferase (26 Jun 1999) |
| polypeptide N-acetylgalactosominyltransferase | <enzyme> N-acetylgalactosaminyl residue is transferred to threonine or serine hydroxyl groups Registry number: EC 2.4.1.41 Synonym: protein-udpacetylgalactosaminyltransferase, udp-n-acetylgalactosamine mucin transferase, udp-n-acetylgalactosamine-polypeptide n-acetylgalactosamine transferase, udpacetylgalactosamine-protein acetylgalactosaminyltransferase, udp-gpagat, udp-galnac-polypeptide, n-acetylgalactosaminyltransferase, galnac-transferase, udp-galnac-polypeptide n-acetylgalactosaminyltransferase (26 Jun 1999) |
| trefoil polypeptide | A group of polypeptides that share the trefoil moiety of a highly stable three-loop structure held together by disulfide bonds based on cysteine residues; they are widely expressed in gastrointestinal tissues and secreted by mucous cells; their functions are as yet unknown. (05 Mar 2000) |
| adenoid tissue | A structure found within the lymphatic system that consists of lymphocytes within a network of fibres. (09 Oct 1997) |
| adipose tissue | <anatomy> Connective tissue that has been specialised to store fat. See: adipocyte. (25 Jun 1999) |
| aerenchymous tissue | A type of plant tissue in which cells are unusually large, resulting in large air spaces in the plant organ, such tissues are often referred to as spongy and usually provide increased buoyancy. (09 Oct 1997) |
| areolar tissue | Loose, irregularly arranged connective tissue that consists of collagenous and elastic fibres, a protein polysaccharide ground substance, and connective tissue cells (fibroblasts, macrophages, mast cells, and sometimes fat cells, plasma cells, leukocytes, and pigment cells). (05 Mar 2000) |
| bone tissue | A connective tissue, the matrix of which consists of collagen fibres and ground substance and in which are deposited calcium salts (phosphate, carbonate, and some fluoride) in the form of an apatite. Synonym: bone tissue. (05 Mar 2000) |
