CC -!- FUNCTION: Regulatory subunit of cyclin-dependent kinases that mediates
CC activation of target kinases. Plays a role in transcriptional
CC regulation via its role in regulating the phosphorylation of the C-
CC terminal domain (CTD) of the large subunit of RNA polymerase II
CC (POLR2A). {ECO:0000269|PubMed:22012619}.
CC -!- SUBUNIT: Regulatory subunit of cyclin-dependent kinases. Identified in
CC a complex with a kinase and the RNA polymerase II holoenzyme. Interacts
CC with POLR2A. Interacts with CDK12 and CDK13. Its interaction with CDK9
CC is controversial. {ECO:0000269|PubMed:22012619}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305|PubMed:22012619}.
CC -!- TISSUE SPECIFICITY: Ubiquitously expressed. Highest levels in testis.
CC Present throughout the seminiferous epithelium. Also highly expressed
CC in the developing oocyte.
CC -!- DEVELOPMENTAL STAGE: Found in 12.5 dpc embryo with abundant expression
CC in eye (retinal pigment epithelium) and ear (cochlea, crista ampullaris
CC of the semicircular canals).
CC -!- DISRUPTION PHENOTYPE: Complete embryonic lethality. No homozygous
CC embryos are detected at any stage of embryonic development.
CC {ECO:0000269|PubMed:22012619}.
CC -!- SIMILARITY: Belongs to the cyclin family. Cyclin C subfamily.
CC {ECO:0000305}.
