What (who) is cyclin - definition

GROUP OF PROTEINS
Mitotic cyclin; Cyclins; Cyclin d1; Cyclin F; Cyklin; Cyclin box
  • Tertiary structure of human cyclin A (lacking the amino-terminal 170 amino acids), showing the central core of two five-helix bundles, with additional helices at the amino terminus (black) and carboxyl terminus (grey). The yellow region in helix 1 is the MRAIL sequence or hydrophobic patch, which contributes to the recognition of some substrates. (PDB 1fin)

Cyclin         
Cyclin is a family of proteins that controls the progression of a cell through the cell cycle by activating cyclin-dependent kinase (CDK) enzymes or group of enzymes required for synthesis of cell cycle.

  • Gap phase 2]].
  • Cyclin binding alone causes partial activation of Cdks, but complete activation also requires activating phosphorylation by a CAK. In animal cells, CAK phosphorylates the Cdk subunit only after cyclin binding, as shown here. Budding yeast contains a different version of CAK that can phosphorylate the Cdk even in the absence of cyclin, and so the two activation steps can occur in either order.
CLASS OF ENZYMES
Cyclin dependent kinase; Cyclin dependent kinases; Cyclin-dependent kinases; Cyclin-dependent kinase inhibitor proteins; Cyclin-Dependent Kinase; CDk; EC 2.7.11.22; NCLK; ATP:cyclin phosphotransferase
Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells.
