Factors controlling cyclin b expression
WebAug 2, 2024 · Mutations of the four MSA-core elements of the cyclin B gene, which encodes a central factor of the G2-to-M-phase transition, have resulted in the abolishment of transcription or permission... WebDec 1, 2024 · In response to DNA damage, cyclin F is able to bind to B-MYB, and rather than ubiquitinate it, inhibits the ability of B-MYB to promote the expression of mitotic genes (Klein et al., 2015). In G2, cyclin F ubiquitinates the stem-loop binding protein (SLBP), which is required during S-phase to mediate histone biogenesis ( Dankert et al., 2016 ).
