Accessory component of the DNA polymerase epsilon complex (By similarity). Participates in DNA repair and in chromosomal DNA replication (By similarity). Histone-like protein which promotes nucleosome sliding of ATP-dependent nucleosome remodeling complexes (PubMed:10856248, PubMed:11447119, PubMed:18327268). 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-16, binds DNA and facilitates nucleosome sliding by Acf (PubMed:16260604). Has a role in DNA damage response by preventing cid mislocalization to chromatin (PubMed:24703848). Homodimer (PubMed:18327268). Component of the DNA polymerase epsilon complex consisting of four subunits: the catalytic subunit PolE1/DNApol-epsilon255 and the accessory subunits PolE2/DNApol-epsilon58, Chrac-14/DNApolE3 and PolE4 (By similarity). Component of the chromatin accessibility complex (CHRAC), composed of Chrac-14, Chrac-16, Acf and Iswi (PubMed:10856248, PubMed:11447119). Forms an heterodimer with Chrac-16 (PubMed:10856248, PubMed:16260604). The Chrac-14/Chrac-16 heterodimer interacts with Acf (via N-terminus) (PubMed:16260604). Interacts directly with Iswi and this interaction is further stabilized by association with Chrac-16 (PubMed:10856248). Component of the Ada2a-containing (ATAC) complex composed of at least Ada2a, Atac1, Hcf, Ada3, Gcn5, Mocs2B, Charac-14, Atac3, Atac2, NC2beta and wds (PubMed:18327268). Interacts with cid (PubMed:24703848). Expressed in oocytes and in the early embryo and down-regulated afterwards (at protein level).
