Summary: Enables ATP-dependent chromatin remodeler activity; DNA translocase activity; and lysine-acetylated histone binding activity. Involved in several processes, including DNA repair; chromatin remodeling; and transcription elongation by RNA polymerase II. Located in nucleus. Part of RSC-type complex. Human ortholog(s) of this gene implicated in Coffin-Siris syndrome 4; Nicolaides-Baraitser syndrome; blepharophimosis-impaired intellectual development syndrome; carcinoma (multiple); and rhabdoid tumor predisposition syndrome 2. Orthologous to several human genes including SMARCA4 (SWI/SNF related BAF chromatin remodeling complex subunit ATPase 4). [provided by Alliance of Genome Resources, Jan 2025]

The wild-type bromodomain preferentially recognizes H3K14ac and H4K20ac peptides. Mutagenesis studies-guided by the crystal structure revealed loop residues Ser1276 and Trp1338 as key determinants for such interactions. Strikingly, point mutations of each of these residues substantially increased peptide binding affinity and selectivity, respectively.

Sliding-to-ejection involves a continuum of DNA translocation efficiency, consistent with higher magnitudes of ATPase and coupling activities (involving ARPs and Sth1 domains), enabling the simultaneous rupture of multiple histone-DNA contacts facilitating ejection.
