Espin, also known as autosomal recessive deafness type 36 protein or ectoplasmic specialization protein, is a protein that in humans is encoded by the ESPN gene. ^[5] Espin is a microfilament binding protein.

Function

Espin is a multifunctional actin-bundling protein. It plays a major role in regulating the organization, dimensions, dynamics, and signaling capacities of the actin filament-rich, microvillus-type specializations that mediate sensory transduction in various mechanosensory and chemosensory cells. ^[5]

Clinical significance

Mutations in this gene are associated with autosomal recessive neurosensory deafness, autosomal dominant sensorineural deafness without vestibular involvement, and DFNB36. ^[5]
