The complex is involved in cell cycle regulation by phosphorylating an activating residue in the T-loop domain of cdks (1). Regulation of CAK activity is mediated by T-loop phosphorylation and by association with MAT1, both of which enhance its kinase activity toward the CTD of RNA polymerase II (2,3) and other substrates such as p53 (4). CAK is an essential component of the transcription complex TFIIH and may interact directly with TFIIH helicases (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n39 kDa protein kinase; CAK; CAK1; CDK-activating kinase; CDK-activating kinase 1; CDK7; CDKN7; Cell division protein kinase 7; cyclin dependent kinase 7; Cyclin-dependent kinase 7; cyclin-dependent kinase 7 (MO15 homolog, Xenopus laevis, cdk-activating kinase); HCAK; homolog of Xenopus MO15 Cdk-activating kinase; kinase subunit of CAK; MO15; p39 Mo15; p39MO15; serine\/threonine kinase stk1; serine\/threonine protein kinase 1; serine\/threonine protein kinase MO15; Serine\/threonine-protein kinase 1; STK1; TFIIH basal transcription factor complex kinase subunit\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 40\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799501099177,"sku":"42863S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-42863s","provider":"Iright","version":"1.0","type":"link"}
