Probing the ligand binding specificity of FNBP4 WW domains and interaction with FH1 domain of FMN1.

ABSTRACT: Formins are a group of actin-binding proteins that mediate nascent actin filament polymerization, filament elongation, and barbed end-capping function, thereby regulating different cellular and developmental processes. Developmental processes like vertebrate gastrulation, neural growth cone dynamics, and limb development require formins functioning in a regulated manner. Formin-binding proteins like Rho GTPase regulate the activation of auto-inhibited conformation of diaphanous formins. Unlike other diaphanous formins, Formin1 (FMN1) a non-diaphanous formin is not regulated by Rho GTPase. FMN1 acts as an antagonist of the Bone Morphogenetic Protein (BMP) signaling pathway during limb development. Several previous reports demonstrated that WW domain-containing proteins can interact with pol
