We purified from rat brain a novel F-actin-binding protein with a Mr of about 105,000 (p105), which was estimated by SDS-polyacrylamide gel electrophoresis. We cloned its cDNA from a rat brain cDNA library and characterized it. p105 was a protein of 766 amino acids and showed a calculated Mr of 86,449. p105 consisted of one F-actin-binding domain at the N-terminal region, one Dbl homology domain and one pleckstrin homology domain at the middle region, and one cysteine-rich domain at the C-terminal region. This domain organization of p105 was similar to that of FGD1, which has been determined to be the genetic locus responsible for faciogenital dysplasia or Aarskog-Scott syndrome. We therefore named p105 frabin (FGD1-related F-actin-binding protein). Frabin bound along the sides of F-actin and showed F-actin-cross-linking activity. Overexpression of frabin in Swiss 3T3 cells and COS7 cells induced cell shape change and c-Jun N-terminal kinase activation, respectively, as described for FGD1. Because FGD1 has been shown to serve as a GDP/GTP exchange protein for Cdc42 small G protein, it is likely that frabin is a direct linker between Cdc42 and the actin cytoskeleton.
