Geminin function
WebThe geminin protein functions both as a DNA rereplication inhibitor through association with Cdt1 and as a repressor of Hox gene transcription through the polycomb pathway. … WebWe summarize the role of Geminin in cell cycle, in the embryonic patterning controlled by Hoxgenes, providing insights into cell cycle regulators in embryonic development, and conversely, typical developmental control genes in cell cycle regulation.

WebAug 8, 2013 · Geminin binds and inhibits Cdt1, thus preventing re-replication in the S-G 2 phases. For this function, the nucleocytoplasmic shuttling of geminin has been reported to play an important role in Xenopus and in avian systems (17, 19). WebNov 24, 2009 · To test the function of Geminin variants we measured their ability to inhibit licensing of sperm DNA in a Xenopus egg extract. We first compared the inhibitory activity of h tGem (which can support heterohexamer formation together with Cdt1) with that of h vtGem (which cannot support heterohexamer formation).
