    Summary
    The protein encoded by this gene is a serine-threonine kinase that is closely related to other kinases that interact with members of the Rho family of small GTPases. Substrates for this enzyme include myogenin, the beta-subunit of the L-type calcium channels, and phospholemman. The 3' untranslated region of this gene contains 5-38 copies of a CTG trinucleotide repeat. Expansion of this unstable motif to 50-5,000 copies causes myotonic dystrophy type I, which increases in severity with increasing repeat element copy number. Repeat expansion is associated with condensation of local chromatin structure that disrupts the expression of genes in this region. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2016]

    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 (3) has multiple differences in the presence and absence of exons at its 5' end and in the CDS, compared to variant 1. These differences produce a distinct 5' UTR, cause translation initiation at an alternative start codon, and the loss of an in-frame portion of the coding region, compared to variant 1. The encoded protein (isoform 3, also known as isoform 11) has a distinct N-terminus and is shorter than isoform 1.

      Description
      Transcript Variant: This variant (2) has multiple differences in the presence and absence of exons at its 5' end, compared to variant 1. These differences produce a distinct 5' UTR and cause translation initiation at an alternative start codon, compared to variant 1. The encoded protein (isoform 2, also known as isoform 9) has a distinct N-terminus and is shorter than isoform 1.
