Cyclin D—INK4 cell cycle regulatory module. Cyclin D1 is encoded by the CCND1 gene. It binds to CDK4 that phosphorylates and inactivates retinoblastoma (Rb), thereby promoting G1/S cell cycle progression. Cyclin D1 overexpression is observed mainly in nonfunctioning and aggressive pituitary tumors and is not a frequent event in
A cyclin subtype that is specific for CYCLIN-DEPENDENT KINASE 4 and CYCLIN-DEPENDENT KINASE 6. Unlike most cyclins, cyclin D expression is not cyclical, but rather it is expressed in response to proliferative signals. Cyclin D may therefore play a role in cellular responses to mitogenic signals.
When quiescent cells enter cycle, genes encoding D-type cyclins (D1, D2, and D3) are induced in response to mitogenic signals, and the cyclins assemble with their catalytic partners, CDK4 and CDK6, as cells progress through G 1 phase (Sherr 1993; Fig. ). "Cyclin D" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. Cyclin D:Cdk4/6 mono-phosphorylation of Rb simultaneously inactivates Rb's G 0 functions and activates Rb's early G 1 phase functions thereby driving cells from a low metabolism G 0 quiescence into a high metabolism early G 1 arrested state that also prevents subsequent cell Cyclin D Family.

Podtyp cyklin, který je specifický pro cyklin-dependentních kináz 4 a cyklin-dependentní kinázy 6. Na rozdíl od většiny cyklinů, cyklin D výraz není cyklické, ale je vyjádřena v reakci na proliferativních signálů.
Cyclin D1 overexpression is observed mainly in nonfunctioning and aggressive pituitary tumors and is not a frequent event in corticotropinomas (Jordan et al., 2000). The cyclin D/CDK4/6 action is inhibited by the INK4 family of CDK inhibitors (p16, p18, and p19). p16/INK4 is encoded by the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene. 2013-05-06 · Research over the past quarter century has identified cyclin D-dependent kinases, CDK4 and CDK6, as the major oncogenic drivers among members of the CDK superfamily. CDK4/6 are rendered Cyclin D is required for passage of the restriction point before S-phase Antibodies to cyclin D were injected into specific cells and their passage into S-phase was arrested. Cells were incubated with the thymidin analoug BrdU (Bromo-deoxyUracil) to study DNA syntesis.

doi: 10.1038/35014621. Authors C E Cockcroft 1 , B G The Cyclin D/Cdk4 complex is a multi-protein structure consisting of the proteins Cyclin D and cyclin-dependent kinase 4, or Cdk4, a serine-threonine kinase.This complex is one of many cyclin/cyclin-dependent kinase complexes that are the "hearts of the cell-cycle control system" and govern the cell cycle and its progression. The cyclin D–CDK4/6–pRb axis unequivocally plays a pivotal role in the regulation of cellular proliferation and transformation. However, recent studies have identified additional cyclin D–CDK4/6 substrates that likely contribute to the proliferative drive imposed by cyclin D–CDK4/6 activation . A particularly relevant example is the Cyclin D3 A broadly expressed type D cyclin.

Complexes of the cyclin-dependent kinase, cdk4, and each of three different D-type cyclins, assembled in insect Sf9 cells, phosphorylated a pRb fusion protein in vitro at sites identical to those phosphorylated in human T cells. Only D-type cyclins activated cdk4 enzyme activity, whereas cyclins A, B1, and E did not.

Cyclin D is a member of the cyclin protein family that is involved in regulating cell cycle progression. The synthesis of cyclin D is initiated during G1 and drives the G1/S phase transition. Cyclin D protein is anywhere from 155 (in zebra mussel) to 477 (in Drosophila) amino acids in length.
