| super- | 1. <prefix> A prefix signifying above, over, beyond, and hence often denoting in a superior position, in excess, over and above, in addition, exceedingly; as in superimpose, supersede, supernatural, superabundance. 2. <chemistry> A prefix formerly much used to denote that the ingredient to the name of which it was prefixed was present in a large, or unusually large, proportion as compared with the other ingredients; as in calcium superphosphate. It has been superseded by per-, bi-, di-, acid, etc. (as peroxide, bicarbonate, disulphide, and acid sulphate), which retain the old meanings of super-, but with sharper definition. Cf. Acid, Bi-, Di-, and Per-. Origin: L. Super over, above; akin to Gr, L. Sub under, and E. Over. See Over, and cf. Hyper-, Sub-, Supra-, Sur-. (29 Oct 1998) |

| gene products, rev | Trans-acting nuclear proteins whose functional expression are required for HIV viral replication. Specifically, the rev gene products are required for processing and translation of the HIV gag and env mRNAs, and thus rev regulates the expression of the viral structural proteins. Rev can also regulate viral regulatory proteins. A cis-acting antirepression sequence (car) in env, also known as the rev-responsive element (rre), is responsive to the rev gene product. Rev is short for regulator of virion. (12 Dec 1998) |
| genes, rev | DNA sequences that form the coding region for a protein that regulates the expression of the viral structural and regulatory proteins in human immunodeficiency virus (HIV). Rev is short for regulator of virion. (12 Dec 1998) |
| rev | <molecular biology> A regulatory protein produced by HIV within infected cells. Rev helps transport HIV RNA sequences (messenger RNA) out from the nucleus into the cells cytoplasm, where it directs construction of proteins for new virus particles. (11 Jan 1998) |
