Recombinant Human TRIO and F-actin-binding protein (TRIOBP), Truncated

Uniprot Id

Q9H2D6

Target Species

Human

Target Name

TRIOBP

Target Full Name

TRIO and F-actin-binding protein

Target Function

May regulate actin cytoskeletal organization, cell spreading and cell contraction by directly binding and stabilizing filamentous F-actin. The localized formation of TARA and TRIO complexes coordinates the amount of F-actin present in stress fibers. May also serve as a linker protein to recruit proteins required for F-actin formation and turnover.

Target Involvement

Deafness, autosomal recessive, 28 (DFNB28)

Target Subcellular Location

Nucleus. Cytoplasm, cytoskeleton.; [Isoform 1]: Nucleus. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Midbody.

Target Tissue Specificity

Widely expressed. Highly expressed in heart and placenta. Isoform 3 is expressed in fetal brain, retina and cochlea but is not detectable in the other tissues.

Target Synonyms

TRIOBP; KIAA1662; TARA; HRIHFB2122; TRIO and F-actin-binding protein; Protein Tara; Trio-associated repeat on actin

Target Background

This gene encodes a protein with an N-terminal pleckstrin homology domain and a C-terminal coiled-coil region. The protein interacts with trio, which is involved with neural tissue development and controlling actin cytoskeleton organization, cell motility and cell growth. The protein also associates with F-actin and stabilizes F-actin structures. Mutations in this gene have been associated with a form of autosomal recessive nonsyndromic deafness. Multiple alternatively spliced transcript variants that would encode different isoforms have been found for this gene, however some transcripts may be subject to nonsense-mediated decay (NMD).
