Protein
Actin-related protein 4
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Function
Chromatin interaction component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histone H4 and H2A. The NuA4 complex is also involved in DNA repair. Is required for NuA4 complex integrity. Component of the SWR1 complex which mediates the ATP-dependent exchange of histone H2A for the H2A variant HZT1 leading to transcriptional regulation of selected genes by chromatin remodeling. Component of the INO80 complex which remodels chromatin by shifting nucleosomes and is involved in DNA repair (By similarity).
Similarity
Belongs to the actin family. ARP4 subfamily.
