COMMENT     REVIEWED REFSEQ: This record has been curated by NCBI staff. The
            reference sequence was derived from HY147073.1, AK290390.1 and
            On Mar 1, 2014 this sequence version replaced XP_005269620.1.
            Summary: This gene produces alternative transcripts encoding two
            distinct proteins. One protein is a transcriptional repressor,
            while the other isoform is a major component of specialized
            synapses known as synaptic ribbons. Both proteins contain a NAD+
            binding domain similar to NAD+-dependent 2-hydroxyacid
            dehydrogenases. A portion of the 3' untranslated region was used to
            map this gene to chromosome 21q21.3; however, it was noted that
            similar loci elsewhere in the genome are likely. Blast analysis
            shows that this gene is present on chromosome 10. Several
            transcript variants encoding two different isoforms have been found
            for this gene. [provided by RefSeq, Feb 2014].
            Transcript Variant: This variant (5) contains a distinct 5' UTR and
            5' CDS, compared to variant 2. Variants 1, 3, 4, and 5-8 all encode
            the same isoform (1), which has a distinct N-terminus that is 540
            aa shorter than the N-terminus of isoform 2. The protein is thought
            to bind to the C-terminus of the adenovirus E1A proteins. Studies
            in mice suggest that this protein is involved in transcriptional
            Sequence Note: This RefSeq record was created from transcript and
            genomic sequence data to make the sequence consistent with the
            reference genome assembly. The genomic coordinates used for the
            transcript record were based on transcript alignments.

            publications that are available for this gene. Please see the Gene
