Evolution of the Cdk4/6–Cdkn2 system in invertebrates

open access: yesGenes to Cells, Volume 29, Issue 11, Page 1037-1051, November 2024.
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.
