    Summary
    This gene encodes a large abundant protein of striated muscle. The product of this gene is divided into two regions, a N-terminal I-band and a C-terminal A-band. The I-band, which is the elastic part of the molecule, contains two regions of tandem immunoglobulin domains on either side of a PEVK region that is rich in proline, glutamate, valine and lysine. The A-band, which is thought to act as a protein-ruler, contains a mixture of immunoglobulin and fibronectin repeats, and possesses kinase activity. An N-terminal Z-disc region and a C-terminal M-line region bind to the Z-line and M-line of the sarcomere, respectively, so that a single titin molecule spans half the length of a sarcomere. Titin also contains binding sites for muscle associated proteins so it serves as an adhesion template for the assembly of contractile machinery in muscle cells. It has also been identified as a structural protein for chromosomes. Alternative splicing of this gene results in multiple transcript variants. Considerable variability exists in the I-band, the M-line and the Z-disc regions of titin. Variability in the I-band region contributes to the differences in elasticity of different titin isoforms and, therefore, to the differences in elasticity of different muscle types. Mutations in this gene are associated with familial hypertrophic cardiomyopathy 9, and autoantibodies to titin are produced in patients with the autoimmune disease scleroderma.

    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.

      Transcript Variant: This variant (IC) represents an inferred complete model that includes all possible supported in-frame coding exons. The exons included in this inferred variant are supported by the original sequence analysis, publication data(PMID:11717165), available cDNA and EST data, and additional sequence analysis of the repetitive exons. This transcript is the longest and represents a 363-exon model encoding a predicted protein (isoform IC) of 35,991 amino acids.

      Description
      Transcript Variant: This variant (N2-B) encodes the major cardiac muscle isoform (N2-B). It lacks multiple exons in the region encoding PEVK repeats. This results in a shortened PEVK region in isoform N2-B compared to isoform IC. This variant is supported by data in PMIDs 10850961 and 11717165.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (N2-A) encodes isoform N2-A, which is the predominant titin isoform in skeletal muscle. This variant lacks the N2B region but includes the PEVK region. This variant is supported by data in PMIDs 7569978, 10850961 and 11717165.
