MGI Phenotype FUNCTION: This gene encodes a protein with similarity to members of the myosin light chain kinase family. This protein family is required for myocyte cytoskeletal development. Studies have determined that a lack of this protein affected myocardial development. Multiple alternatively spliced transcript variants that encode different protein isoforms have been defined. [provided by RefSeq, Mar 2010]
PHENOTYPE: Mice homozygous for a knock-out allele die during the early postnatal period with enlarged, dilated hearts, and decreased cardiac function. [provided by MGI curators]
