Regulates the transcriptional activity of DNTT and ESR1. May function as a chromatin remodeling protein. Forms a ternary complex with DNTT and core histone; interaction with PCNA releases DNTT and H2A/H2B histones from this ternary complex. Interacts with ESR1, ESR2, PPARG and RXRA. Widely expressed with higher levels in testis. Contaminating sequence. Potential poly-A sequence.
