F PF05856 ARPC4 ARP2/3 complex 20 kDa subunit (ARPC4) Family
E PF04062 P21-Arc ARP2/3 complex ARPC3 (21 kDa) subunit Family
G PF04699 P16-Arc ARP2/3 complex 16 kDa subunit (p16-Arc) Domain The Arp2/3 protein complex has been implicated in the control of actin polymerisation. The human complex consists of seven subunits which include the actin related proteins Arp2 and Arp3, and five others referred to as p41-Arc, p34-Arc, p21-Arc, p20-Arc, and p16-Arc. The precise function of p16-Arc is currently unknown. Its structure consists of a single domain containing a bundle of seven alpha helices [1,2]. PFAM PF04699
