Histone-like protein which promotes nucleosome sliding of ATP-dependent nucleosome remodeling complexes (PubMed:10856248, PubMed:11447119). Part of the chromatin-accessibility complex (CHRAC) which uses energy/ATP to increase the general accessibility of DNA in chromatin (PubMed:10856248, PubMed:11447119). As an heterodimer with Chrac-14, binds DNA and facilitates nucleosome sliding by Acf (PubMed:16260604). As part of the CHRAC complex, required for oogenesis (PubMed:26851213). Component of the chromatin accessibility complex (CHRAC), composed of Chrac-14, Chrac-16, Acf and Iswi (PubMed:10856248, PubMed:10731132). Forms an heterodimer with Chrac-14 (PubMed:10856248, PubMed:16260604). The Chrac-14/Chrac-16 heterodimer interacts with Acf (via N-terminus) (PubMed:16260604). Stabilizes the interaction between Chrac-14 and Iswi (PubMed:10856248). Expressed in nurse cells and oocytes of all stages (PubMed:26851213). Expressed in oocytes and embryos and down-regulated afterwards (PubMed:10856248).
