該基因編碼細胞周期蛋白依賴性蛋白激酶（cdk）家族的一個成員。cdk家族成員是細胞周期進展的重要調節者。這種激酶及其調節亞單位，細胞周期蛋白c，是介體轉錄調節復合物的組成部分，參與轉錄激活和rna聚合酶ii最大亞單位羧基末端結構域磷酸化的抑制。該激酶通過靶向一般轉錄起始因子iih的細胞周期蛋白依賴性激酶7亞單位來調節轉錄，從而在介體復合體和基礎轉錄機制之間提供一個連接。已鑒定出該基因的多個假基因。選擇性剪接導致多個轉錄變體。[由RefSeq提供，2016年10月]
This gene encodes a member of the cyclin-dependent protein kinase (CDK) family. CDK family members are known to be important regulators of cell cycle progression. This kinase and its regulatory subunit, cyclin C, are components of the Mediator transcriptional regulatory complex, involved in both transcriptional activation and repression by phosphorylation of the carboxy-terminal domain of the largest subunit of RNA polymerase II. This kinase regulates transcription by targeting the cyclin-dependent kinase 7 subunits of the general transcription initiation factor IIH, thus providing a link between the Mediator complex and the basal transcription machinery. Multiple pseudogenes of this gene have been identified. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2016]
