Protein diaphanous homolog 1 is a protein that in humans is encoded by the DIAPH1 gene.

Function

This gene is a homolog of the Drosophila diaphanous gene and belongs to the protein family of the formins, characterized by the formin homology 2 (FH2) domain. It has been linked to autosomal dominant, fully penetrant, nonsyndromic sensorineural progressive low-frequency hearing loss. Actin polymerization involves proteins known to interact with diaphanous protein in Drosophila and mouse. It has therefore been speculated that this gene may have a role in the regulation of actin polymerization in hair cells of the inner ear. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

Interactions

DIAPH1 has been shown to interact with RHOA.

Clinical significance

Mutations in this gene have been associated with macrothrombocytopenia and hearing loss, microcephaly, blindness, and early onset seizures

Its actions on platlet formation appear to occur at the level of the megakaryocyte where it is involved in cytoskeleton formation.
