WebNX_Q96EP1 - CHFR - E3 ubiquitin-protein ligase CHFR - Function. E3 ubiquitin-protein ligase that functions in the antephase checkpoint by actively delaying passage into mitosis in response to microtubule poisons. Acts in early prophase before chromosome condensation, when the centrosome move apart from each other along the periphery of the nucleus. WebCheckpoint with forkhead and RING finger domains protein (CHFR) is an E3 ubiquitin-protein ligase that regulates cell cycle progression. In response to microtubule stress, CHFR delays the transition into mitosis by excluding cyclin B1 from the nucleus prior to chromosome condensation (1). Marked reduction of CHFR expression was detected in ...

WebMay 14, 2010 · CHFR functions as a mitotic checkpoint by delaying entry into metaphase in response to mitotic stress. CHFR is frequently silenced by hypermethylation in human cancers, indicating that CHFR is a tumor suppressor. To further elucidate the role of CHFR in tumorigenesis, we studied the relationship between CHFR and a novel CHFR … WebJan 21, 2002 · When the Chfr protein was incubated with radioactive ubiquitin in the presence of the recombinant E1 and Ubc4, ubiquitin conjugates were efficiently formed (Fig. 1 C). These conjugates were resistant to reduction by DTT, suggesting that ubiquitin is conjugated through an isopeptide bond rather than a thioester bond.
