| adenovirus early proteins | <molecular biology, protein, virology> Proteins encoded by adenoviruses that are synthesised prior to, and in the absence of, viral DNA replication. The proteins are involved in both positive and negative regulation of expression in viral and cellular genes, and also affect the stability of viral mRNA. Some are also involved in oncogenic transformation. (12 Dec 1998) |
|---|---|
| amino acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
| androgen-binding proteins | Carrier proteins produced in the sertoli cells of the testis, secreted into the seminiferous tubules, and transported via the efferent ducts to the epididymis. Participate in the transport of androgens; include also synthetic androgens binding proteins. (12 Dec 1998) |
| archaeal proteins | Proteins found in any species of archaeon. (12 Dec 1998) |
| bacterial outer membrane proteins | Proteins isolated from the outer membrane of bacteria. (12 Dec 1998) |
| bacterial proteins | Proteins found in any species of bacterium. (12 Dec 1998) |
| basic proteins | Proteins that are rich in basic amino acids; e.g., histones. (05 Mar 2000) |
| Bence Jones proteins | Proteins with unusual thermosolubility found in the urine of patients with multiple myeloma, consisting of monoclonal immunoglobulin light chains. See: Bence Jones reaction. See: immunoglobulin. (05 Mar 2000) |
| blood proteins | The hundreds of different proteins present in blood plasma, including carrier proteins (such as serum albumin, transferrin, and haptoglobins), fibrinogen and other blood coagulation factors, complement components, immunoglobulins, enzyme inhibitors, precursors of substances such as the angiotensins and bradykinin, and many other types of proteins. (12 Dec 1998) |
| bone morphogenetic proteins | Non-collagenous factors, believed to be proteins, that occur in demineralised bone and stimulate osteogenesis. They can induce new bone formation in ectopic sites and thus have potential use in bone repair. (12 Dec 1998) |
| calmodulin-binding proteins | Proteins which bind calmodulin. They are found in many tissues and have a variety of functions including f-actin cross-linking properties, inhibition of cyclic nucleotide phosphodiesterase and calcium and magnesium atpases. (12 Dec 1998) |
| capping proteins | Proteins that bind to one end of actin filaments, preventing both addition and loss of actin monomers. (05 Mar 2000) |
| vegetable proteins | Proteins which are present in or isolated from vegetables or vegetable products used as food. The concept is distinguished from plant proteins which refers to non-dietary proteins from plants. (12 Dec 1998) |
| ras proteins | Small GTP-binding proteins encoded by ras genes (genes, ras) that play a critical role in normal cellular growth, differentiation, and development, and have the potential for malignant transformation. Two of the major ras proteins include the normal cellular form, proto-oncogene protein p21(ras), and the malignant form, oncogene protein p21(ras). (12 Dec 1998) |
| recombinant fusion proteins | Proteins that are the result of genetic engineering. A regulatory part or promoter of one or more genes is combined with a structural gene. The fusion protein is formed after transcription and translation of the fused gene. This type of fusion protein is used in the study of gene regulation or structure-activity relationships. They might also be used clinically as targeted toxins (immunotoxins). (12 Dec 1998) |
