mlc-5 encodes a protein containing two EF-hand domains that is the C. elegans myosin II essential light chain ortholog; MLC-5 activity is required for cytokinesis and for epithelial morphogenesis during embryonic elongation; a GFP::MLC-5 fusion protein is expressed during embryogenesis in the lateral hypodermal seam cells as well as in the dorsal and ventral hypodermal cells where it exhibits co-localization with actin bundles; MLC-5 subcellular localization depends upon activity of MLC-4, a myosin regulatory light chain; in turn, MLC-5 activity is required for proper localization of MLC-4 and the non-muscle myosin II NMY-2.
Predicted to enable calcium ion binding activity. Involved in mitotic cytokinesis. Located in actin cytoskeleton. Human ortholog(s) of this gene implicated in congenital myopathy 14; familial atrial fibrillation; and hypertrophic cardiomyopathy 8. Is an ortholog of human MYL4 (myosin light chain 4); MYL6 (myosin light chain 6); and MYL6B (myosin light chain 6B).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
