Summary: This gene encodes 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. Mutations in this gene are associated with autosomal recessive neurosensory deafness, and autosomal dominant sensorineural deafness without vestibular involvement. [provided by RefSeq, Nov 2009]
Expression: Biased expression in testis (RPKM 9.0), skin (RPKM 5.5) and 8 other tissues See more

What's a GeneRIF?

whirlin-espin interaction is important for the architecture of the USH2 complex and actin bundles cross-linked by espin. Our demonstration of whirlin N-terminal fragment interaction with espin, is significantly novel, providing insight into how these two proteins interact to form the USH2 complex.

ur study uncovers an additional USH gene, assigns the USH1 phenotype to a variant of ESPN and provides a 12th molecular component to the USH proteome
Title: Inframe deletion of human ESPN is associated with deafness, vestibulopathy and vision impairment.
A significant inverse correlation was observed between miR-612 and Espin protein expression in melanoma tissues.

The utricles were then treated with a gamma-secretase inhibitor, followed by espin or control transduction and histochemistry. Although gamma-secretase inhibition increased the number of HCs, few had stereociliary arrays. In contrast, 46 h after espin1 transduction, a significant increase in hair-bundle-like structures was observed

The structures of Myo3 in complex with Espin1 not only elucidate the mechanism of the binding, but also reveal a Myo3-induced release of Espin1 auto-inhibition mechanism.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
