This gene encodes a member of the atrophin family of arginine-glutamic acid (RE) dipeptide repeat-containing proteins. The encoded protein co-localizes with a transcription factor in the nucleus, and its overexpression triggers apoptosis. A similar protein in mouse associates with histone deacetylase and is thought to function as a transcriptional co-repressor during embryonic development. Multiple transcript variants encoding different isoforms have been found for this gene.,RERE,ARG,ARP,ATN1L,DNB1,NEDBEH,Epigenetics & Nuclear Signaling,Transcription Factors,Cell Biology & Developmental Biology,Apoptosis,Caspases,RERE
