    Summary
    This gene encodes an intracellular calcium-binding protein belonging to the troponin C superfamily. Members of this protein family have six EF-hand domains which bind calcium. This protein plays a role in diverse cellular functions, including message targeting and intracellular calcium buffering. It also functions as a modulator of neuronal excitability, and is a diagnostic marker for some human diseases, including Hirschsprung disease and some cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 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 (CALB2c) lacks an alternate segment in the 3' coding region, which results in a frameshift and an early stop codon, compared to variant 1. The resulting protein (isoform 22k) has a shorter and distinct C-terminus, compared to isoform 1. There are no publicly available transcripts supporting this variant; it is represented based on data in PMID:7607211.

    RNA

    1. NR_027910.3 RNA Sequence

      Status: REVIEWED

      Description
      Transcript Variant: This variant (CALB2b) lacks an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD). This variant was described by Schwaller et al (PMID: 7607211), and proposed to encode a 20kDa isoform, but this protein has not been shown to be expressed in vivo.
