The CCNT1 Antibody from MyBioSource.com is a Rabbit Polyclonal antibody to CCNT1. This antibody recognizes Human antigen. The CCNT1 Antibody has been validated for the following applications: ELISA, Immunohistochemistry, and Western Blot.
Description
Function: Regulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin-T1) complex, also called positive transcription elongation factor B (P-TEFb), which is proposed to facilitate the transition from abortive to productive elongation by phosphorylating the CTD (carboxy-terminal domain) of the large subunit of RNA polymerase II (RNA Pol II).
Subunit Structure: Cyclin-T1 is the predominant cyclin that associates with CDK9 to form a heterodimer called P-TEFb. P-TEFb forms a complex with AFF4/AF5Q31. Component of a complex which is at least composed of HTATSF1/Tat-SF1, P-TEFb complex, RNA pol II, SUPT5H, and NCL/nucleolin (PubMed:10393184). Component of the 7SK snRNP complex at least composed of P-TEFb (composed of CDK9 and CCNT1/cyclin-T1), HEXIM1, HEXIM2, BCDIN3, SART3 proteins and 7SK and U6 snRNAs (PubMed:17643375). Interacts with BRD4, probably to target chromatin binding (PubMed:16109376, PubMed:16109377). Interacts with MDFIC (PubMed:12944466). Interacts with HSF1 (PubMed:27189267). Interacts with HTATSF1 (PubMed:10913173). Interacts with AFF4 (PubMed:12065898). Interacts with TBX21 (PubMed:27292648).
Similarity: Belongs to the cyclin family. Cyclin C subfamily
