Summary: The protein encoded by this gene is a nuclear receptor coactivator that interacts with nuclear hormone receptors to enhance their transcriptional activator functions. The encoded protein has histone acetyltransferase activity and recruits p300/CBP-associated factor and CREB binding protein as part of a multisubunit coactivation complex. This protein is initially found in the cytoplasm but is translocated into the nucleus upon phosphorylation. Several transcript variants encoding different isoforms have been found for this gene. In addition, a polymorphic repeat region is found in the C-terminus of the encoded protein. [provided by RefSeq, Mar 2010]
Annotation information: Note: RAC3 (Gene ID: 5881) and NCOA3 (Gene ID: 8202) share the RAC3 symbol/alias in common. RAC3 is a widely used alternative name for nuclear receptor coactivator 3 (NCOA3), which can be confused with the official symbol for ras-related C3 botulinum toxin substrate 3 (RAC3). [06 Jul 2018]
Expression: Ubiquitous expression in lymph node (RPKM 20.8), placenta (RPKM 19.0) and 25 other tissues See more

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
