We identify two phosphorylation sites in the VCA domain of WASP at serines 483 and 484. S483 and S484 are substrates for casein kinase 2 in vitro and in vivo. Phosphorylation of these residues increases the affinity of the VCA domain for the Arp2/3 complex 7-fold and is required for efficient in vitro actin polymerization by the full-length WASP molecule. |

TCR-induced WASp tyrosine phosphorylation was also disrupted in T cells lacking Fyn, a kinase shown here to bind, colocalize with, and phosphorylate WASp. Although Fyn enhanced WASp-mediated Arp2/3 activation and was required for synapse formation, PTP-PEST combined with PSTPIP1 inhibited WASp-driven actin polymerization and synapse formation. |

Hck induces tyrosine phosphorylation of WASp. Here we show that the Src family kinase Hck induces phosphorylation of WASp-Tyr(291) independently of Cdc42 and that this causes a shift in the mobility of WASp upon SDS-PAGE. A phospho-mimicking mutant, WASp-Y291E, exhibited an enhanced ability to stimulate actin polymerization in a cell-free system and when microinjected into primary macrophages induced extensive filopodium formation with greater efficiency than wild-type WASp or a Y291F mutant. We propose that phosphorylation of Tyr(291) directly regulates WASp function. |

We demonstrated that WASP is phosphorylated on tyrosine 291 in macrophages, and the WASP phosphorylation is important for the phagocytic cup formation. In addition, we showed that WASP and WASP-interacting protein (WIP) form a complex at the phagocytic cup and that the WASP.WIP complex plays a critical role in the phagocytic cup formation. |
