Cyclin B, cyclin B1
The protein encoded by this gene is a regulatory protein involved in mitosis. The gene product complexes with p34(cdc2) to form the maturation-promoting factor (MPF). Two alternative transcripts have been found, a constitutively expressed transcript and a cell cycle-regulated transcript, that is expressed predominantly during G2/M phase. The different transcripts result from the use of alternate transcription initiation sites. [provided by RefSeq, Jul 2008] (from

We conducted real-time PCR on cells grown in 2D culture and 3D scaffolds for the proliferation markers cyclin B1 and E2F1 and the actin regulator RhoA, and found a significant decrease in expression levels for the 3D tumour models (p = 0.02, < 0.001 and 0.008 for cyclin B1, E2F1 and RhoA for 143.98.2; p = 0.02, 0.002 and 0.02 for cyclin B1, E2F1 and RhoA for U2OS, respectively).

Here, we identify that cyclin B1/CDK1-phosphorylates iASPP, which leads to the inhibition of iASPP dimerization, promotion of iASPP monomer nuclear entry, and exposure of its p53 binding sites, leading to increased p53 inhibition.

In the Xenopus laevis embryonic cell cycle oscillator, this loop consists of the kinase cyclin B-Cdk1 and the ubiquitin ligase APC/C(Cdc20); active Cdk1 activates APC/C(Cdc20), which then brings about cyclin B degradation and inactivates Cdk1.
First polar body (PBI) extrusion is triggered by the inactivation of cyclin-dependent kinase 1 (CDK1), following the degradation of its regulatory subunit cyclin B1 by the ubiquitin proteasome pathway.

Fifteen years ago, it was proposed that the cell cycle in fission yeast can be driven by quantitative changes in the activity of a single protein kinase complex comprising a cyclin - namely cyclin B - and cyclin dependent kinase 1 (Cdk1).

The switch between E2F1 and E2F4 at the E2F binding site of the cyclinB1 promoter coincides with an androgen-dependent interaction between AR and E2F1 as well as the cytoplasmic-to-nuclear translocation of E2F4.
