Function

Actin nucleation and elongation factor required for the assembly of F-actin structures, such as actin cables and stress fibers (By similarity). Binds to the barbed end of the actin filament and slows down actin polymerization and depolymerization (By similarity). Required for cytokinesis, and transcriptional activation of the serum response factor (By similarity). DFR proteins couple Rho and Src tyrosine kinase during signaling and the regulation of actin dynamics (By similarity). Functions as a scaffold protein for MAPRE1 and APC to stabilize microtubules and promote cell migration (By similarity). Has neurite outgrowth promoting activity. Acts in a Rho-dependent manner to recruit PFY1 to the membrane (By similarity). In hear cells, it may play a role in the regulation of actin polymerization in hair cells (PubMed:20937854, PubMed:21834987, PubMed:26912466). The MEMO1-RHOA-DIAPH1 signaling pathway plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex (PubMed:20937854, PubMed:21834987). It controls the localization of APC and CLASP2 to the cell membrane, via the regulation of GSK3B activity (PubMed:20937854, PubMed:21834987). In turn, membrane-bound APC allows the localization of the MACF1 to the cell membrane, which is required for microtubule capture and stabilization (PubMed:20937854, PubMed:21834987). Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape (PubMed:20937854, PubMed:21834987). Plays a role in brain development (PubMed:24781755). Also acts as an actin nucleation and elongation factor in the nucleus by promoting nuclear actin polymerization inside the nucleus to drive serum-dependent SRF-MRTFA activity (By similarity).

Activity summary

DIAPH1 also known as Diaphanous-related formin 1 operates mainly in actin polymerization and is critical for filament formation. It weighs approximately 140 kDa. DIAPH1 expresses in a variety of tissues including heart liver and kidney making it a target of interest in multiple biological contexts. The protein plays a role in maintaining proper cytoskeletal dynamics by regulating the assembly of actin filaments.

Biological function summary

DIAPH1 functions as part of the formin family which are important in cytoskeletal organization. It interacts with other proteins to initiate and elongate actin filaments often acting within larger protein complexes that control cellular morphology and movement. DIAPH1 contributes to muscle contraction cell division and cell migration highlighting its importance in cellular structure and dynamics.

Pathways

DIAPH1 plays a significant role in the Rho GTPase signaling pathway. This pathway connects to cytoskeleton remodeling impacting cell shape and movement. DIAPH1 associates with proteins like RhoA which regulates its activity. Additionally DIAPH1 influences the Wnt signaling pathway known for its involvement in cell proliferation and differentiation.

Associated diseases and disorders

DIAPH1 is connected to a form of sensorineural hearing loss and leukemia. Mutations in DIAPH1 can lead to autosomal dominant deafness as it affects the proper maintenance of actin structures in hair cells within the inner ear. The protein also interacts with genes linked to cancer development including those coding for p53 influencing tumorigenesis and cell cycle regulation.
