This locus represents naturally occurring read-through transcription from the neighboring IQ motif containing J (Iqcj) and schwannomin interacting protein 1 (Schip1) genes. This locus produces a transcript that is composed of in-frame exons from each individual gene. The resulting fusion protein is thought to be a component of the multimolecular complexes of axon initial segments and nodes of Ranvier, and it may play a role in calcium-mediated responses.
