The crystal structure of cyclin A [PDF]
Structure, 1995 Eukaryotic cell cycle progression is regulated by cyclin dependent protein kinases (CDKs) whose activity is regulated by association with cyclins and by reversible phosphorylation. Cyclins also determine the subcellular location and substrate specificity of CDKs.

Distinct properties of cyclin-dependent kinase complexes containing cyclin A1 and cyclin A2 [PDF]
Biochemical and Biophysical Research Communications, 2009 The distinct expression patterns of the two A-type cyclins during spermatogenesis and the absolute requirement for cyclin A1 in this biological process in vivo suggest that they may confer distinct biochemical properties to their CDK partners. We therefore compared human cyclin A1- and cyclin A2-containing CDK complexes in vitro by determining kinetic ...

Molecular and Cellular Biology, 1994 Herpesvirus saimiri contains an open reading frame called eclf2 with homology to the cellular type D cyclins. We now show that the eclf2 gene product is a novel virus-encoded cyclin (v-cyclin). The protein encoded by the v-cyclin gene of this oncogenic herpesvirus was found to have an apparent molecular size of 29 kDa in transformed cells.

, 2006 D type cyclins belong to a family of related proteins that bind to and activate several protein kinases named cyclin-dependent kinases (CDKs), which are involved in regulation of the cell division cycle.

Effect of cyclins and Cdks on the cyclin B1 promoter activation [PDF]
IUBMB Life, 1997 AbstractTo study the effect of several cyclins on cyclin B1 promoter activation, we co‐transfected cyclin A, cyclin E and cyclin D1 expressing plasmids with a cyclin B1 promoter construction driving a luciferase repotnter gene into NIH 3T3 cells. All three cyclins produced activation of the reporter gene, however, co‐transfection of cyclin A with a ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Molecular Oncology, EarlyView.Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Cytometry of cyclin proteins [PDF]
Cytometry, 1996 Cyclins are key components of the cell cycle progression machinery. They activate their partner cyclin-dependent kinases (CDKs) and possibly target them to respective substrate proteins within the cell. CDK-mediated phosphorylation of specific sets of proteins drives the cell through particular phases or checkpoints of the cell cycle.

Molecular Oncology, Volume 19, Issue 6, Page 1725-1736, June 2025.Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.
