| RNA-binding proteins | Proteins which bind to RNA molecules. Certain structure motifs are common to several of the proteins, such as arginine (arg)-rich tracts, typically consisting of alternating arg-asp, arg-ser, or arg-gly residues. These proteins also tend to have a common ribonucleotide sequence domain. (12 Dec 1998) |
|---|---|
| cholesterol ester transport proteins | A protein that transports cholesterol esters from HDL to VLDL and LDL; a deficiency of this protein is associated with elevated HDL cholesterol. (05 Mar 2000) |
| chromosomal proteins, non-histone | Nucleoproteins which in contrast to histones are acid insoluble. They are involved in chromosomal functions; e.g. They bind selectively to DNA, stimulate transcription resulting in tissue-specific RNA synthesis and undergo specific changes in response to various hormones or phytomitogens. (12 Dec 1998) |
| microfilament proteins | Filaments which are composed primarily of actin and found in the cytoplasmic matrix of almost all cells. They are often associated with microtubules and may play a role in cytoskeletal function and/or mediate movement of the cell or the organelles within the cell. (12 Dec 1998) |
| microtubule-associated proteins | <protein> High molecular weight proteins found in the microtubules of the cytoskeletal system. Under certain conditions they are required for tubulin assembly into the microtubules and stabilise the assembled microtubules. Acronym: MAP (12 Dec 1998) |
| milk proteins | The major protein constituents of milk are caseins and whey proteins such as lactalbumin and lactoglobulins. Immunoglobulins occur in high concentrations in colostrum and in relatively lower concentrations in milk. (12 Dec 1998) |
| phosphorylation of proteins | <biochemistry> Addition of phosphate groups to hydroxyl groups on proteins (side chains s, T or Y) catalysed by a protein kinase often specific) with ATP as phosphate donor. Activity of proteins is often regulated by phosphorylation. (18 Nov 1997) |
| clathrin adaptor proteins | <cell biology> Family of proteins that bind to clathrin and promote its assembly into vesicle coats. Different adaptor proteins are associated with coated vesicles of Golgi or plasma membrane origin. (18 Nov 1997) |
| monocyte chemoattractant proteins | Chemokines that are chemoattractants for monocytes. These cc chemokines (cysteines adjacent) number at least three including monocyte chemoattractant protein-1. (12 Dec 1998) |
| monosaccharide transport proteins | Membrane transport proteins which bind glucose and sodium ions and enter the cell together. The sodium ions are then pumped out of the cell by a sodium potassium atpase. The rate and extent of the sugar transport depends on the sodium ion concentration. Inhibitors of the monosaccharide transport system are phlorizin, cytochalasin b, and inhibitors of the sodium potassium atpase system. Insulin increases the rate of monosaccharide transport across the membrane into the cell. (12 Dec 1998) |
| plant proteins | Proteins found in plants (flowers, herbs, shrubs, trees, etc.). The concept does not include proteins found in vegetables for which vegetable proteins is available. (12 Dec 1998) |
| m proteins | Antibodies or parts of antibodies found in unusually large amounts in the blood or urine of multiple myeloma patients. (12 Dec 1998) |
| plasma proteins | Dissolved protein's (more than 100) of blood plasma, mainly albumins and globulins (normally 6 to 8 g/100 ml); they hold fluid in blood vessels by osmosis and include antibodies and blood-clotting protein's. Synonym: serum proteins. (05 Mar 2000) |
| muscle proteins | The protein constituents of muscle, the major ones being actins and myosin. More than a dozen accessary proteins exist including troponin, tropomyosin, and dystrophin. (12 Dec 1998) |
| contractile proteins | Proteins which participate in contractile processes. They include muscle proteins as well as those found in other cells and tissues. In the latter, these proteins participate in localised contractile events in the cytoplasm, in motile activity, and in cell aggregation phenomena. (12 Dec 1998) |
