Function

[DIAP1_MOUSE] Acts in a Rho-dependent manner to recruit PFY1 to the membrane. Required for the assembly of F-actin structures, such as actin cables and stress fibers. Nucleates actin filaments. Binds to the barbed end of the actin filament and slows down actin polymerization and depolymerization. Required for cytokinesis, and transcriptional activation of the serum response factor. DFR proteins couple Rho and Src tyrosine kinase during signaling and the regulation of actin dynamics. Functions as a scaffold protein for MAPRE1 and APC to stabilize microtubules and promote cell migration. Has neurite outgrowth promoting activity. The MEMO1-RHOA-DIAPH1 signaling pathway plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex. It controls the localization of APC and CLASP2 to the cell membrane, via the regulation of GSK3B activity. In turn, membrane-bound APC allows the localization of the MACF1 to the cell membrane, which is required for microtubule capture and stabilization. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape (By similarity).^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Diaphanous-related formins (Drf) are activated by Rho GTP binding proteins and induce polymerization of unbranched actin filaments. They contain three formin homology domains. Evidence as to the effect of formins on actin polymerization were obtained using FH2/FH1 constructs of various length from different Drfs. Here we define the core FH2 domain as a proteolytically stable domain of approximately 338 residues. The monomeric FH2 domains from mDia1 and mDia3 inhibit polymerization of actin and can bind in a 1:1 complex with F-actin at micromolar concentrations. The X-ray structure analysis of the domain shows an elongated, crescent-shaped molecule consisting of three helical subdomains. The most highly conserved regions of the domain span a distance of 75 A and are both required for barbed-end inhibition. A construct containing an additional 72 residue linker has dramatically different properties: It oligomerizes and induces actin polymerization at subnanomolar concentration.

The core FH2 domain of diaphanous-related formins is an elongated actin binding protein that inhibits polymerization.,Shimada A, Nyitrai M, Vetter IR, Kuhlmann D, Bugyi B, Narumiya S, Geeves MA, Wittinghofer A Mol Cell. 2004 Feb 27;13(4):511-22. PMID:14992721^[5]
