| 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) |
| recombinant proteins | Proteins prepared by recombinant DNA technology. (12 Dec 1998) |
| carrier proteins | Transport proteins that carry specific substances in the blood or across cell membranes. (12 Dec 1998) |
| matrix proteins | Proteins of the outer layer of the cell wall of gram-negative bacteria. (18 Nov 1997) |
| viral core proteins | Proteins found mainly in icosahedral DNA and RNA viruses. They consist of proteins directly associated with the nucleic acid inside the nucleocapsid. (12 Dec 1998) |
| viral envelope proteins | Layers of protein which surround the capsid in animal viruses with tubular nucleocapsids. The envelope consists of an inner layer of lipids and virus specified proteins also called membrane or matrix proteins. The outer layer consists of one or more types of morphological subunits called peplomers which project from the viral envelope; this layer always consists of glycoproteins. (12 Dec 1998) |
| viral fusion proteins | Proteins, usually glycoproteins, found in the viral envelopes of a variety of viruses. They promote cell membrane fusion and thereby may function in the uptake of the virus by cells. (12 Dec 1998) |
