Summaries for DIAPH3 Gene

Entrez Gene Summary for DIAPH3 Gene

  • This gene encodes a member of the diaphanous subfamily of the formin family. Members of this family are involved in actin remodeling and regulate cell movement and adhesion. Mutations in this gene are associated with autosomal dominant auditory neuropathy 1. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

GeneCards Summary for DIAPH3 Gene

DIAPH3 (Diaphanous-Related Formin 3) is a Protein Coding gene. Diseases associated with DIAPH3 include auditory neuropathy, autosomal dominant, 1 and auditory neuropathy. Among its related pathways are Regulation of actin cytoskeleton and ERK Signaling. GO annotations related to this gene include actin binding and Rho GTPase binding. An important paralog of this gene is FMN2.

UniProtKB/Swiss-Prot for DIAPH3 Gene

  • Binds to GTP-bound form of Rho and to profilin. Acts in a Rho-dependent manner to recruit profilin to the membrane, where it promotes actin polymerization. It is required for cytokinesis, stress fiber formation, and transcriptional activation of the serum response factor. DFR proteins couple Rho and Src tyrosine kinase during signaling and the regulation of actin dynamics (By similarity).

  • Q9NSV4
  • The DAD domain regulates activation via by an autoinhibitory interaction with the GBD/FH3 domain. This autoinhibition is released upon competitive binding of an activated GTPase. The release of DAD allows the FH2 domain to then nucleate and elongate nonbranched actin filaments (By similarity).
  • Contains 1 DAD (diaphanous autoregulatory) domain.
  • Contains 1 FH1 (formin homology 1) domain.
  • Contains 1 FH2 (formin homology 2) domain.
  • Contains 1 GBD/FH3 (Rho GTPase-binding/formin homology 3) domain.
  • Belongs to the formin homology family. Diaphanous subfamily.

Disorders for DIAPH3 Gene

(1) OMIM Diseases for DIAPH3 Gene (614567)


  • Auditory neuropathy, autosomal dominant, 1 (AUNA1) [MIM:609129]: A form of sensorineural hearing loss with absent or severely abnormal auditory brainstem response, in the presence of normal cochlear outer hair cell function and normal otoacoustic emissions. Auditory neuropathies result from a lesion in the area including the inner hair cells, connections between the inner hair cells and the cochlear branch of the auditory nerve, the auditory nerve itself and auditory pathways of the brainstem. {ECO:0000269 PubMed:20624953}. Note=The disease is caused by mutations affecting the gene represented in this entry. A disease-causing mutation in the conserved 5-UTR leads to increased protein expression (PubMed:20624953). {ECO:0000269 PubMed:20624953}.
