The protein encoded by this gene binds to both CDC42 and N-WASP. This protein promotes CDC42-induced actin polymerization by activating the N-WASP-WIP complex and, therefore, is involved in a pathway that links cell surface signals to the actin cytoskeleton. Alternative splicing results in multiple transcript variants encoding different isoforms.[4]
Clinical significance[]
FNBP1Lpolymorphisms, specifically the SNP rs236330 has been associated with normally varying intelligence differences in adults[5] and in children.[6]
