Figure 3. The putative phosphorylation sites are conserved. (A) Phosphorylated T237, T238, and Y202 of Arp2 were mapped to the Arp2/3 complex crystal structure obtained by Robinson et al. (2001). From the crystal structure, T237 and T238 of Arp2 are adjacent to R105 and R106 of ARPC4, and Y202 of Arp2 is adjacent to R409 of Arp3. (inset) Enlarged view of the boxed region. (B) The proposed phosphorylation sites on the Arp2 subunit and adjacent arginine residues in ARPC4 and Arp3 are conserved in nine organisms.
