Protein diaphanous homolog 1 is a protein that in humans is encoded by the DIAPH1 gene.^[4][5][6]

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.^[6]

Interactions

DIAPH1 has been shown to interact with RHOA.^[7]
