肌动蛋白相关蛋白（Arps）：染色质重塑机器的构象开关？

Actin-related proteins (Arps): conformational switches for chromatin-remodeling machines? Actin-related proteins (Arps): conformational switches for chromatin-remodeling machines? Laurie A. Boyer and Craig L. Peterson* Summary The actin superfamily of ATPases includes cytoskeletal actins, the stress 70 proteins (e.g. hsc70), sugar kinases, glycerol kinase, and several prokaryotic cell cycle proteins. Although these proteins share limited sequence identity, they all appear to maintain a simila
