Recombinant Human Protein diaphanous homolog 3 (DIAPH3), Truncated

Uniprot Id

Q9NSV4

Target Species

Human

Target Name

DIAPH3

Target Full Name

Protein diaphanous homolog 3

Target Function

Actin nucleation and elongation factor required for the assembly of F-actin structures, such as actin cables and stress fibers. Required for cytokinesis, stress fiber formation and transcriptional activation of the serum response factor. 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. DFR proteins couple Rho and Src tyrosine kinase during signaling and the regulation of actin dynamics. 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.

Target Involvement

Auditory neuropathy, autosomal dominant, 1 (AUNA1)

Target Subcellular Location

Cytoplasm. Nucleus.

Target Protein Families

Formin homology family, Diaphanous subfamily

Target Background

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.
