Summaries for CHN1 Gene

Entrez Gene Summary for CHN1 Gene

  • This gene encodes GTPase-activating protein for ras-related p21-rac and a phorbol ester receptor. It is predominantly expressed in neurons, and plays an important role in neuronal signal-transduction mechanisms. Mutations in this gene are associated with Duane's retraction syndrome 2 (DURS2). Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Apr 2011]

GeneCards Summary for CHN1 Gene

CHN1 (Chimerin 1) is a Protein Coding gene. Diseases associated with CHN1 include duane retraction syndrome 2 and duane retraction syndrome. Among its related pathways are Signaling by GPCR and Signaling by Rho GTPases. GO annotations related to this gene include GTPase activator activity and ephrin receptor binding. An important paralog of this gene is ABR.

UniProtKB/Swiss-Prot for CHN1 Gene

  • GTPase-activating protein for p21-rac and a phorbol ester receptor. Involved in the assembly of neuronal locomotor circuits as a direct effector of EPHA4 in axon guidance.

  • Duane retraction syndrome 2 (DURS2) [MIM:604356]: Duane retraction syndrome is a congenital eye movement disorder characterized by a failure of cranial nerve VI (the abducens nerve) to develop normally, resulting in restriction or absence of abduction, adduction, or both, and narrowing of the palpebral fissure and retraction of the globe on attempted adduction. Undiagnosed in children, it can lead to amblyopia, a permanent uncorrectable loss of vision. {ECO:0000269 PubMed:18653847}.
