Cyclin T2

cyclin T2a, cyclin T2, CycT2, cyclin T2b
The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin and its kinase partner CDK9 were found to be subunits of the transcription elongation factor p-TEFb. The p-TEFb complex containing this cyclin was reported to interact with, and act as a negative regulator of human immunodeficiency virus type 1 (HIV-1) Tat protein. A pseudogene of this gene is found on chromosome 1. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Dec 2010] (from NCBI)

Genetic analysis of the structure and function of 7SK small nuclear ribonucleoprotein (snRNP) in cells.
Peterlin et al., In J Biol Chem, 2014
The positive transcription elongation factor b (P-TEFb), comprised of cyclin-dependent kinase 9 (CDK9) and cyclins T1 (CycT1) or T2 (CycT2), activates eukaryotic transcription elongation.
Release of positive transcription elongation factor b (P-TEFb) from 7SK small nuclear ribonucleoprotein (snRNP) activates hexamethylene bisacetamide-inducible protein (HEXIM1) transcription.
Peterlin et al., San Francisco, United States. In J Biol Chem, 2014
By phosphorylating negative elongation factors and the C-terminal domain of RNA polymerase II (RNAPII), positive transcription elongation factor b (P-TEFb), which is composed of CycT1 or CycT2 and CDK9, activates eukaryotic transcription elongation.
Activation and function of murine Cyclin T2A and Cyclin T2B during skeletal muscle differentiation.
Bagella et al., Sassari, Italy. In J Cell Biochem, 2013
The regulatory units of Cdk9 are the T family Cyclins (T1, T2) and Cyclin K. Cyclin T2 has two forms termed Cyclin T2a and Cyclin T2b that arise by an alternative splicing of the primary transcript.
MicroRNA-29a and microRNA-142-3p are regulators of myeloid differentiation and acute myeloid leukemia.
Zhang et al., Beijing, China. In Blood, 2012
Both the miRNAs directly inhibited cyclin T2 gene, preventing the release of hypophosphorylated retinoblastoma and resulting in induction of monocytic differentiation.

HSV-1 stimulation-related protein HSRG1 inhibits viral gene transcriptional elongation by interacting with Cyclin T2.
Li et al., Kunming, China. In Sci China Life Sci, 2011
Yeast two-hybrid and immunoprecipitation assays indicated that HSRG1 interacts with Cyclin T2, the regulatory subunit of P-TEFb, which is required for transcription elongation by RNA Pol II (RNAP II), and that amino acid residues 1-420 in Cyclin T2 are important for binding with HSRG1.
