| glycine-rich beta-glycoprotein | <enzyme> A glycine-rich, heat-labile beta-glycoprotein found in blood. It is a proactivator of complement 3 in the alternate pathway of complement activation. Factor b is converted by factor d to c3 convertase. Registry number: EC 3.4.21.47 (12 Dec 1998) |

| glycoprotein | <protein> Proteins with covalently attached sugar units, either bonded via the OH group of serine or threonine O glycosylated) or through the amide NH2 of asparagine (N glycosylated). Includes most secreted proteins (serum albumin is the major exception) and proteins exposed at the outer surface of the plasma membrane. Sugar residues found include: mannose, N acetyl glucosamine, N acetyl galactosamine, galactose, fucose and sialic acid. (18 Nov 1997) |
| glycoprotein endo-alpha-1,3-mannosidase | <enzyme> An endomannosidase; cleaves glucosyl alpha1-3-mannose from monoglucosylated oligosaccharide (glcman(7-9)glcnac) of the glycoprotein produced in the golgi membrane Registry number: EC 3.2.1.130 Synonym: glucosyl mannosidase (26 Jun 1999) |
| glycoprotein glycosyltransferase | <enzyme> Enzymes which add monosaccharides from nucleoside mono-or diphosphate monosaccharides onto glycoproteins Registry number: EC 2.4.1.- (26 Jun 1999) |
| glycoprotein hormones, alpha subunit | A non-covalently bound subunit of the glycoprotein hormones tsh, fsh, lh, and hcg which originates in the anterior pituitary gland and placenta. This subunit is virtually identical in structure and indistinguishable by radioimmunoassay in all of the above glycoproteins. It is present in both men and women, but is elevated in postmenopausal women and in patients with hypothyroidism, uraemia and malignant tumours. The alpha subunit may be involved directly in recognition of certain receptors. (12 Dec 1998) |
| glycoprotein hormone-specific N-acetylgalactosamine transferase | <enzyme> Transfers galnac to the terminal glcnac moieties of glcnac2man3glcnac2asn Registry number: EC 2.4.1.- Synonym: ghs-acgalnh2 transferase, glycoprotein hormone galnac transferase, glycoprotein hormone - n-acetylgalactosaminyltransferase (26 Jun 1999) |
| glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase | <enzyme> Forms o-glycan core i; forms galactosyl beta 1,3-n-acetylgalactosaminide mucin Registry number: EC 2.4.1.122 Synonym: udp-galactose-n-acetylgalactosamine-alpha-r beta3-galactosyltransferase, glycoprotein-galnac-galactosyltransferase, gp galnac gal transferase, core I beta3-galactosyltransferase, galnac-1-o-ser or thr 1-3 galactosyltransferase, udp-gal-n-acetylgalactosaminide mucin-beta 1,3-galactosyltransferase, udpgal-nacgm-galactosyltransferase, udp-galactose-alpha-n-acetylgalactosaminide beta 3 galactosyltransferase (26 Jun 1999) |
| p-glycoprotein | <cell biology, protein> A family of integral plasma membrane proteins which, when overexpressed, function as adenosine triphosphate-dependent efflux pumps, causing multidrug resistance. Mammalian p-glycoproteins are encoded by small mdr gene families. There are several isotypes in multiple species. See: multidrug transporter. (22 Sep 2002) |
| platelet glycoprotein gpib-ix complex | Platelet membrane glycoprotein complex essential for normal platelet adhesion and clot formation at sites of vascular injury. It is composed of three polypeptides, gpib alpha, gpib beta, and gpix. Glycoprotein ib functions as a receptor for von willebrand factor and for thrombin. Congenital deficiency of the gpib-ix complex results in bernard-soulier syndrome. The platelet glycoprotein gpv associates with gpib-ix and is also absent in bernard-soulier syndrome. (12 Dec 1998) |
| platelet glycoprotein gpiib-iiia complex | Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. The complex is an integrin which recognises the arginine-glycine-aspartic acid (rgd) sequence present on several adhesive proteins. As such, it is a receptor for fibrinogen, von willebrand factor, fibronectin, vitronectin, and thrombospondin. A deficiency of gpiib-iiia results in glanzmann's thrombasthenia. (12 Dec 1998) |
| mucus glycoprotein sulfotransferase | <enzyme> Specific for gastric mucus sulfation Registry number: EC 2.8.2.- Synonym: mucus gp sulfotransferase (26 Jun 1999) |
| pregnancy-specific beta 1-glycoprotein | A glycoprotein with the electrophoretic mobility of a beta-1 globulin. It is produced by the placental trophoblast and secreted into the maternal bloodstream during pregnancy. It can be detected 18 days after ovulation and its concentration in plasma rises steadily until, at the end of gestation, it reaches 200 mg/ml. It has been proposed as a measure of placental function for fertility control and is a candidate for an early pregnancy test. (12 Dec 1998) |

| invariant surface glycoprotein 100 | <chemical> A stage-specific invariant surface protein in trypanosoma brucei containing an internal, serine-rich, repetitive motif; amino acid sequence given in first source; genbank y14833 Synonym: isg-100 (05 Dec 1998) |
| Thy 1 glycoprotein | <cell biology, immunology> A molecule of 19 kD found on the surface of lymphoid and brain tissues of some mammals. Used as a marker for T lymphocytes in those species displaying it. Two allelic forms are known, Thy 1a, Thy 1b, determining Thy 1.1. And Thy 1.2. Molecules respectively, formerly known as _ AKR and _ C3H respectively. Functions unclear. (18 Nov 1997) |
