abstractText | mDia1 is a downstream effector of Rho small G protein that is implicated in stress fiber formation and cytokinesis. We isolated an mDia1-binding protein and identified it to be IRSp53/BAIAP2. IRSp53 and BAIAP2 have independently been isolated as a 58/53-kDa protein tyrosine phosphorylated in response to insulin and a BAI1-binding protein, respectively. BAI1 is a brain-specific seven-span transmembrane protein capable of inhibiting angiogenesis. The proline-rich formin homology 1 domain of mDia1 bound the Src homology 3 domain of IRSp53/BAIAP2 in a GTP-Rho-dependent manner. The results suggest that IRSp53/BAIAP2 is a downstream effector of mDia1. Copyright 2000 Academic Press. |
