This entry represents actin-related protein 8 and plant actin-related protein 9 (Arp8/plant Arp9). Plant Arp9 is a homologue of Arp8 [PMID: 15063870]. Arp8 plays an important role in the functional organisation of mitotic chromosomes. It exhibits low basal ATPase activity, and it is unable to polymerise [PMID: 22977180]. Arp8 is proposed core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair [PMID: 18163988].
