MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene belongs to the innexin family. Innexin family members are the structural components of gap junctions. This protein and pannexin 1 are abundantly expressed in central nervous system (CNS) and are coexpressed in various neuronal populations. Studies in Xenopus oocytes suggest that this protein alone and in combination with pannexin 1 may form cell type-specific gap junctions with distinct properties. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit a slight protection from the neurological defects induced by ischemic brain injury. [provided by MGI curators]

Nature of Mutation
DNA sequencing using the SOLiD technique identified a T to C transition at position 1027 of the Panx2 transcript in exon 2 of 3 total exons.  Two transcripts of the Panx2 gene are displayed at Ensembl. The mutated nucleotide causes a tyrosine to histidine substitution at amino acid 227 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
 
Protein Function and Prediction
The Panx2 gene encodes a 677 amino acid structural component of gap junctions known as Pannexin-2. Pannexin-2 forms heteromeric channels with Pannexin-1 (Uniprot Q6IMP4).    
 
The Y227H change is predicted to be possibly damaging by the PolyPhen program.
