FAMILY

CATEGORY

regulatory

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus

basic FUNCTION	involved in late G1 to S transition regulator of the cell cycle
	ubiquitin conjugating enzyme E2, required for the poly ubiquitination of NFKBI
	E2-conjugating enzyme required for catalyzing the polyubiquitination reaction mediated by the Skp1.CUL1.F-box (SCF) protein E3 ubiquitin (Ub) ligase (Gazdoiu 2005)
	controls cellular proliferation through regulation of CDKN1B protein levels (Butz 2005)
	catalyzes polyubiquitination of a substrate recruited by the Skp1-Cullin 1-F-box protein-ROC1 E3 Ub ligase (Gazdoiu 2007)
	employs distinct sites to coordinate attachment of ubiquitin to a substrate and assembly of polyubiquitin chains (Gazdoiu 2007)
	plays an essential role in promoting the G1-S-phase transition of the eukaryotic cell cycle (Sadowski 2007)
