Background：Modulates the transcription repressor activity of DAXX by recruiting it to the nucleolus(PubMed:11948183). As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues(PubMed:20018852). Putative regulatory component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair. May also be an inhibitor of TERT telomerase activity(PubMed:15044100). Binds to G-quadruplex structures in mRNA(PubMed:16571602). Binds to RNA homopolymer poly(G) and poly(U)(PubMed:16571602).
