The function of ENSG00000163104 (SMARCAD1, SNF2 related chromatin remodeling ATPase with DExD box 1) is as follows. Protein that possesses intrinsic ATP-dependent nucleosome- remodeling activity and is both required for DNA repair and heterochromatin organization (PubMed:22960744, PubMed:21820097). Combines the ATP-dependent ability to exchange histones, with the chaperone-like ATP-independent activity to deposit histones and assemble nucleosomes (PubMed:21820097). Promotes DNA end resection of double-strand breaks (DSBs) following DNA damage: probably acts by weakening histone DNA interactions in nucleosomes flanking DSBs (PubMed:22960744). Required for the restoration of heterochromatin organization after replication (PubMed:21549307). Acts at replication sites to facilitate the maintenance of heterochromatin by directing H3 and H4 histones deacetylation, H3 'Lys-9' trimethylation (H3K9me3) and restoration of silencing (PubMed:21549307). {ECO:0000269|PubMed:21549307, ECO:0000269|PubMed:21820097, ECO:0000269|PubMed:22960744}.
