Cell division cycle and apoptosis regulator protein 1 (CCAR1)

Associates with elements of the Mediator and p160 coactivator complexes that play a role as intermediaries transducing regulatory signals from upstream transcriptional activator proteins to basal transcription machinery at the core promoter. Recruited to endogenous nuclear receptor target genes in response to the appropriate hormone.

Also functions as a p53 coactivator. May thus play an important role in transcriptional regulation (By similarity).
