| myeloma protein | <haematology, oncology> The immunoglobulins and Bence Jones proteins secreted by myeloma cells. (18 Nov 1997) |
|---|---|
| myod protein | A myogenic regulatory factor that controls myogenesis. Though it is not clear how its function differs from the other myogenic regulatory factors, myod appears to be related to fusion and terminal differentiation of the muscle cell. (12 Dec 1998) |
| C protein | <cell biology> Striated muscle thick filament associated proteins (140-150 kD) that show up in the C zone of the A band as 43nm transverse stripes. Structurally related to various other myosin binding proteins (twitchin, titin, myosin light chain kinase, skelemin, 86 kD protein, projectin, M protein). (18 Nov 1997) |
| myotonin-protein kinase | <enzyme> Has been sequenced Registry number: EC 2.7.- Synonym: mtpk, myotonin protein kinase (26 Jun 1999) |
| C-reactive protein | <protein> This blood test is used as an indicator of acute inflammation. C-reactive protein is a protein of the pentraxin family, produced by the liver during periods of inflammation and detectable in serum in various disease conditions particularly during the acute phase of immune response. Normally C-reactive protein should be negative in the bloodstream. C-reactive protein is synthesised by hepatocytes and its production may be triggered by prostaglandin E1 or parogen. It consists of five polypeptide sub units forming a molecule of total molecular weight 105 kD. It binds to polysaccharides present in a wide range of bacterial, fungal and other cell walls or cell surfaces and to lecithin and to phosphoryl or choline containing molecules. It is related in structure to Serum Amyloid. And C polysaccharide. Conditions which can cause a positive C-reactive protein include: rheumatoid arthritis, lupus, pneumococcal pneumonia, rheumatic fever, cancer, tuberculosis and myocardial infarction. A positive C-reactive protein may also be seen in the later half of pregnancy and in some who are taking birth control pills. See: acute phase proteins (06 Oct 1997) |
| CRK4 protein kinase | <enzyme> From mouse, has 85% amino acid identity with xenopus m015 protein kinase; genbank x74145 Registry number: EC 2.7.10.- Synonym: crk4 pk (26 Jun 1999) |
| H1-related protein-tyrosine phosphatase | <enzyme> Has tyrosine and threonine/serine phosphatase activities Registry number: EC 3.1.3.- Synonym: vaccinia virus h1-related protein tyrosine phosphatase, vhr ptpase, vh-ptp13 (26 Jun 1999) |
| cro protein | <protein> Protein synthesised by bacteriophage lambda in the lytic state. The cro protein blocks the synthesis of the lambda repressor (that is produced in the lysogenic stage and inhibits cro protein synthesis). Production of the cro protein in turn controls a set of genes associated with rapid virus multiplication. (18 Nov 1997) |
| haemagglutinin-neuraminidase protein | <protein> A protein found in the capsid of the Sendai virus which is exceptionally good at binding to the cytoplasmic membranes of many animal cells. The protein is therefore used to make fusogenic vesicles for the purpose of delivering therapeutic drugs or other chemicals directly into cells. (09 Oct 1997) |
| crude protein | Incomplete proteins which lack essential amino acids. (09 Oct 1997) |
| crystalline protein | <protein> The major protein found in the lens of the vertebrate eye, it can be dissolved in water easily. (09 Oct 1997) |
| Csk-like protein-tyrosine kinase | <enzyme> Phosphorylates c-terminal conserved tyr of src family members; from mouse brain; has 52% identity with mouse csk; mw 52 kD; genbank u05210 Registry number: EC 2.7.1.- Synonym: ctk (kinase), ctk gene product, csk-type protein-tyrosine kinase, ntk (kinase), bhk (kinase) (26 Jun 1999) |
| C-terminal leucine protein methyltransferase | <enzyme> Reversibly modifies protein phosphatase 2a by methyl esterification at its c-terminal leucine residues Registry number: EC 2.1.1.- Synonym: tlp methyltransferase (26 Jun 1999) |
| PP5 protein-serine-threonine phosphatase | <enzyme> Has 4 tetratricopeptide repeat (tpr) motifs; similar to ppt1 protein; do not confuse with the placental protein pp5; amino acid sequence given in first source Registry number: EC 3.1.3.- Synonym: pp5 phosphatase, protein phosphatase 5 (26 Jun 1999) |
| pp65 protein | <protein> A protein made by a cytomegalovirus which prevents the cell that the virus has infected from displaying fragments of viral proteins, called antigens, on the cells surface. In this way the cytomegalovirus is able to evade the bodys immune system, more or less permanently. (09 Oct 1997) |
