TRIOBP

The information on this page was automatically extracted from online scientific databases.

What is the official name of the TRIOBP gene?

The official name of this gene is “TRIO and F-actin binding protein.”

TRIOBP is the gene's official symbol. The TRIOBP gene is also known by other names, listed below.

What is the normal function of the TRIOBP gene?

From NCBI Gene (http://www.ncbi.nlm.nih.gov/gene/11078):

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]

From UniProt (TARA_HUMAN) (http://www.uniprot.org/uniprot/Q9H2D6):

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.

How are changes in the TRIOBP gene related to health conditions?

Genetics Home Reference provides information about nonsyndromic hearing loss, which is associated with changes in the TRIOBP gene.
UniProt (TARA_HUMAN) (http://www.uniprot.org/uniprot/Q9H2D6) provides the following information about the TRIOBP gene's known or predicted involvement in human disease.

Deafness, autosomal recessive, 28 (DFNB28): A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. The disease is caused by mutations affecting the gene represented in this entry.

NCBI Gene (http://www.ncbi.nlm.nih.gov/gene/11078) lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the TRIOBP gene.
  • Deafness, autosomal recessive 28
