Summary: Enables myosin light chain binding activity and myosin light chain kinase activity. Involved in several processes, including positive regulation of fast-twitch skeletal muscle fiber contraction; regulation of neuronal synaptic plasticity; and synaptic vesicle transport. Located in several cellular components, including dendritic spine; neuronal cell body; and synaptic vesicle. Human ortholog(s) of this gene implicated in hypertrophic cardiomyopathy 1. Orthologous to human MYLK2 (myosin light chain kinase 2). [provided by Alliance of Genome Resources, Nov 2024]

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.
