Myp, NOL3, Nop30, Nucleolar protein 3, apoptosis repressor ARC, apoptosis repressor with CARD, apoptosis repressor with caspase recruitment domain (CARD), muscle-enriched cytoplasmic protein, nucleolar protein of 30 kDa
NOL3 encodes an anti-apoptotic protein nucleolar protein 3 that has been shown to down-regulate the enzyme activities of caspase 2, caspase 8 and tumor protein p53. Multiple transcript variants encoding different isoforms have been found for NOL3.
