CrkRS (Cdc2-related kinase Arg/Ser) or cyclin-dependent kinase 12 (CKD12) Ibutamoren (MK-677) is a serine/threonine kinase thought to coordinate transcription and RNA splicing. CDK12/CrkRS but usually do not contain CDK9 a presumed partner of cyclin K. Evaluation of comprehensive RNA-Seq data implies that the 65-kDa cyclin K1 isoform may be the mostly expressed type across numerous… Continue reading CrkRS (Cdc2-related kinase Arg/Ser) or cyclin-dependent kinase 12 (CKD12) Ibutamoren (MK-677)
