ARID4A
Template:Short description Template:Infobox gene AT rich interactive domain 4A (RBP1-like), also known as ARID4A, is a protein which in humans is encoded by the ARID4A gene.[1][2][3]
Function
The protein encoded by this gene is a ubiquitously expressed nuclear protein. It binds directly, with several other proteins, to retinoblastoma protein (pRB) which regulates cell proliferation. pRB represses transcription by recruiting the encoded protein. This protein, in turn, serves as a bridging molecule to recruit HDACs and, in addition, provides a second HDAC-independent repression function. The encoded protein possesses transcriptional repression activity. Multiple alternatively spliced transcripts have been observed for this gene, although not all transcript variants have been fully described.[1]
Interactions
ARID4A has been shown to interact with Retinoblastoma protein.[4]
