Abstract
To the Editor, Cyclin-dependent kinases (CDKs) are protein kinases involved in critical cellular processes, such as cell cycle or transcription, whose activity requires association with specific cyclin subunits. Based on sequence similarity, the human genome contains 21 genes encoding CDKs and five additional genes encoding a more distant group of proteins known as CDK-like (CDKL) kinases. The current nomenclature for CDK proteins includes 11 classical CDKs (CDK1–11), two newly proposed family members (CDK12 and 13) and additional proteins whose names are based on the presence of a cyclin-binding element (PFTAIRE and PCTAIRE proteins) or simply based on a sequence relationship with the original CDKs, such as CDC2-like kinases (CDC2L) or cell cycle-related kinases (CCRK)
