Formin binding proteins bear WWP/WW domains that bind proline‐rich peptides and functionally resemble SH3 domains

The formins, proteins involved in murine limb and kidney development, contain a proline‐rich region that matches consensus sequences for Src homology 3 (SH3) ligands. To identify proteins that interact with formins, we used this proline‐rich region to screen mouse limb bud expression libraries for f...
