    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. [provided by RefSeq, Jul 2008]

    NCBI Reference Sequences (RefSeq)

    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.

    mRNA and Protein(s)

    1. NM_001083914.1NP_001077383.1  C-terminal-binding protein 2 isoform 1

      Status: REVIEWED

      Description
      Transcript Variant: This variant (3) contains a distinct 5' UTR and 5' CDS, compared to variant 2. Both variants 1 and 3 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 repression.
