    Summary
    This gene, a muscle member of the immunoglobulin gene superfamily, encodes myosin light chain kinase which is a calcium/calmodulin dependent enzyme. This kinase phosphorylates myosin regulatory light chains to facilitate myosin interaction with actin filaments to produce contractile activity. This gene encodes both smooth muscle and nonmuscle isoforms. In addition, using a separate promoter in an intron in the 3' region, it encodes telokin, a small protein identical in sequence to the C-terminus of myosin light chain kinase, that is independently expressed in smooth muscle and functions to stabilize unphosphorylated myosin filaments. A pseudogene is located on the p arm of chromosome 3. Four transcript variants that produce four isoforms of the calcium/calmodulin dependent enzyme have been identified as well as two transcripts that produce two isoforms of telokin. Additional variants have been identified but lack full length transcripts. [provided by RefSeq, Jul 2008]

    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 (7) encodes the shorter isoform of kinase related protein, telokin. The first exon corresponds to intron 30 and the remainder of the transcript corresponds to the last two exons of the gene. It is shorter than variant 8 by one codon at the splicing junction between the first two exons.

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_005965.3: Suppressed sequence

      Description
      NM_005965.3: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.

    2. NM_053029.2: Suppressed sequence

      Description
      NM_053029.2: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.

    3. NM_053030.2: Suppressed sequence

      Description
      NM_053030.2: This RefSeq was permanently suppressed because there was insufficient support for the transcript and the CDS was partial.
