    Summary
    This gene encodes a protein that is expressed in the brain and may function in neuronal migration, based on functional studies of the related astrotactin 1 gene in human and mouse. A deletion at this locus has been associated with schizophrenia. Multiple transcript variants encoding different proteins have been found for this locus. [provided by RefSeq, May 2010]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (5) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at an alternate start codon, compared to variant 1. This variant also lacks a segment in the 3' coding region compared to variant 1. The encoded isoform (e) has distinct N- and C-termini and is shorter than isoform a.

      Transcript Variant: This variant (6) has multiple differences compared to variant 1. These differences result in a distinct 5' UTR and lead to translation initiation at an alternate start codon, compared to variant 1. The encoded isoform (f) has distinct N- and C-termini and is shorter than isoform a.
