产品说明
一般描述
CDK9/CyclinK, active, GST tagged human comprises recombinant full-length human CDK9 and cyclinK proteins co-expressedin Sf9 insect cells with an N-terminal GST tag. Cyclin-dependent protein kinase 9 (CDK9)/CyclinK is a member of the cyclin-dependent protein kinase (CDK) family. CDK9 is a component of the multiprotein complex mitogen-activated protein kinase 7 and transcription elongation factor β (TAK/P-TEFβ).
生化/生理作用
CDKs are closely related to yeast CDk1, cdc28 and cdc2 and arean important regulators of the cell cycle. CDK9 can modulate RNA polymerase II-directed transcription by phosphorylating the C-terminal domain of the largest subunit of RNA polymerase II. CDK9 forms a complex with and is regulated by its regulatory subunit cyclin T or cyclin K. CDK9 also interacts with the human immune deficiency virus 1 (HIV-1) transactivating regulatory protein (Tat) protein, which suggests a possible involvement of this protein in AIDS.
