Quick Reference

1. Heterogeneous ribonuclear protein U (scaffold attachment factor A, 806 aa), the largest of the major hnRNP proteins: contains an RNA binding domain and a scaffold-associated region (SAR)-specific bipartite DNA-binding domain. It is thought to be involved in the packaging of hnRNA into large ribonucleoprotein complexes.

2. Occasional abbreviation for ‘urinary protein’.

3. (Obsolete) Hypothetical protein (trigger protein) thought to regulate the transition of cells from G0 to G1 phase of the cell cycle. Superseded by cyclins.
