Abstract
Rbx1, an evolutionarily conserved Cullin-interacting RING-H2 finger protein, has been discovered. Mammalian Rbx1 has been identified as a component of the CUL2-containing VHL complex. An Rbx1 homolog fromhas also been identified as a subunit and activator of the Cdc53-containing SCFubiquitin ligase required for ubiquitination of the cdk inhibitor Sic1 and for the G1/S cell cycle transition in yeast, providing a link between the multiprotein VHL tumor suppressor complex and cellular ubiquitination. The Rbx1 protein acts as a cellular marker useful (1) in detecting a possible predisposition to certain carcinomas, (2) as a molecular target for treating those carcinomas therapeutically. (3) as a target for inhibition by drugs that manipulate the growth of cells, and (4) as a research tool to better understand the various complex mechanisms of cell ubiquitination, binding of certain activator proteins, fibronectin deposition and other aspects of the cellular division process.
