Sep 5, 2018 The cyclins, though originally characterized as CDK partners, also have CDK- independent roles that include the regulation of DNA damage 


As we noted earlier, M-Cdk is made up of a Cdk and a cyclin, both of which must be associated for M-Cdk to be active. If cyclin is destroyed, then the levels of active M-Cdk will fall. As M-Cdk levels fall, the cell begins to return to its interphase state.

The Cdk-cyclin complexes regulate a series of events that lead cells from a resting state (G0), growth phase (G1), through DNA replication (S), and finally to cell division (M).

We uncovered a cyclin docking motif, LxF, that mediates binding of replication factor Cdc6 to mitotic cyclin. This interaction leads to phospho-adaptor Cks1-mediated inhibition of M-CDK to facilitate Cdc6 accumulation and sequestration in mitosis. The LxF motif and Cks1 also mediate the mutual inhibition between M-CDK and the tyrosine kinase Swe1. 2019-07-11 Anaphase-promoting complex (also called the cyclosome or APC/C) is an E3 ubiquitin ligase that marks target cell cycle proteins for degradation by the 26S proteasome.The APC/C is a large complex of 11–13 subunit proteins, including a cullin (Apc2) and RING (Apc11) subunit much like SCF.Other parts of the APC/C still have unknown functions, but are highly conserved. Viral cyclin D binds human Cdk6 and inhibits Rb by phosphorylating it, resulting in free transcription factors which result in protein transcription that promotes passage through G1 phase of the cell cycle.

Komplexet utöver detta även "Anaphase promoting komplex", APC. A cell can switch from G0, or cell cycle arrest, to G1 once cells have attained a critical size. For multicellular organisms, growth factors and mitogens, wh Cyclin-dependent kinases (CDKs) are serine/threonine kinases whose catalytic activities are regulated by interactions with cyclins and CDK inhibitors (CKIs). CDKs are key regulatory enzymes involved in cell proliferation through regulating cell-cycle checkpoints and transcriptional events in respons … While activation of APC/C Cdc20 requires M-Cdk, the complex is also responsible for breaking the cyclin to deactivate M-CdK. This means that APC/C Cdc20 fosters its own deactivation. It is possible that this negative feedback is the backbone of Cdk activity controlled by M and S cyclin concentration oscillations.
