| Cek4 receptor protein-tyrosine kinase | <enzyme> Isolated from mouse and chicken. Registry number: EC 2.7.1.- Synonym: cek4 protein, cek4 eph receptor, eph receptor cek4 (26 Jun 1999) |
| cell-free protein synthesis | <technique> An in vitro method to make proteins, using amino acids, the mRNA corresponding to the protein to be made, and a cell-free extract (the contents of a cell after removal of the cell wall and/or outer cell membranes) for other needed components and enzymes. (26 Mar 1998) |
| PCTAIRE-2 protein kinase | <enzyme> Member of a subfamily of cdc-2-related kinases preferentially expressed in post-mitotic cells; amino acid sequence has been determined Registry number: EC 2.7.10.- (26 Jun 1999) |
| vitamin d-binding protein | An alpha-globulin found in the plasma of man and other vertebrates. It is apparently synthesised in the liver and carries vitamin d and its metabolites through the circulation and mediates the response of tissue. It is also known as group-specific component (gc). Gc subtypes are used to determine specific phenotypes and gene frequencies. These data are employed in the classification of population groups, paternity investigations, and in forensic medicine.

| cellular retinoic acid binding protein | <protein> A cytoplasmic fatty acid binding protein that acts as an initial receptor for the putative morphogen, retinoic acid. (18 Nov 1997) |
| glucose related protein | <protein> One of the stress related proteins: identical to endoplasmin. (18 Nov 1997) |
| rep protein | <protein> A protein that triggers a plasmid's replication. An acronym for Repetitive Extragenic Palindromicprotein, this protein is an enzyme produced by a mutant strain of E. Coli that unwinds the DNA helix. (09 Oct 1997) |
| repressor protein | <molecular biology> A protein that binds to an operator of a gene preventing the transcription of the gene. The binding affinity of repressors for the operator may be affected by other molecules. Inducers bind to repressors and decrease their binding to the operator, while co repressors increase the binding. The paradigm of repressor proteins is the lactose repressor protein that acts on the lac operon and for which the inducers are _ galactosides such as lactose, it is a polypeptide of 360 amino acids that is active as a tetramer. Other examples are the lambda repressor protein of lambda bacteriophage that prevents the transcription of the genes required for the lytic cycle leading to lysogeny and the cro protein, also of lambda, which represses the transcription of the lambda repressor protein establishing the lytic cycle. Both of these are active as dimers and have a common structural feature the helix turn helix motif that is thought to bind to DNA with the helices fitting into adjacent major grooves. (18 Nov 1997) |
| VLA protein | <protein> VLA 1 and VLA 2 were originally defined as antigens appearing on the surfaces of T lymphocytes 2-4 weeks after in vitro activation, they are now know to be part of the _ integrin family. Additional members of the subset are now known (VLA 3, VLA 4, VLA 5 and VLA 6), the _ subunits all being identical. Some of the VLA proteins are receptors for collagen, laminin or fibronectin and many are now known to be expressed on cells other than leucocytes. (18 Nov 1997) |

| retinoblastoma protein | <molecular biology, protein> Product of the retinoblastoma tumour suppressor gene. It is a nuclear phosphoprotein hypothesised to normally act as an inhibitor of cell proliferation. Rb protein is absent in retinoblastoma cell lines. It also has been shown to form complexes with the adenovirus e1a protein, the sv40 t antigen, and the human papilloma virus e7 protein. (03 Jul 1999) |
