Toward this, we investigated whether PAK1 contributes to the mechanisms involving the actin-binding and -polymerizing proteins neural Wiskott-Aldrich syndrome protein (N-WASP), cortactin, and ARP2/3 subunits. We found that the actin-polymerizing ARP2/3 subunit p41ARC is usually a PAK1 substrate in skeletal muscle mass cells. Moreover,… Continue reading Supplementary Materials Supplemental Data supp_292_46_19034__index. arm of the cycle remains unresolved.
