Appears to promote apoptosis in a p53/TP53-independent manner. Putative regulatory component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair. Interacts with NOL3; translocates NOL3 into the nucleus and negatively regulated TFPT-induced cell death. Component of the chromatin remodeling INO80 complex; specifically part of a complex module associated with the N-terminus of INO80 (By similarity).
