Summaries for TRIOBP Gene

Entrez Gene Summary for TRIOBP Gene

  • 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). [provided by RefSeq, Nov 2008]

GeneCards Summary for TRIOBP Gene

TRIOBP (TRIO And F-Actin Binding Protein) is a Protein Coding gene. Diseases associated with TRIOBP include Deafness, Autosomal Recessive 28 and Nonsyndromic Deafness. GO annotations related to this gene include ubiquitin protein ligase binding and GTP-Rho binding. An important paralog of this gene is MPRIP.

UniProtKB/Swiss-Prot for TRIOBP Gene

  • 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.
