Predicted to enable ATP binding activity; myosin phosphatase regulator activity; and protein serine/threonine kinase activity. Predicted to be involved in several processes, including muscle cell apoptotic process; regulation of skeletal muscle contraction by calcium ion signaling; and regulation of synapse structural plasticity. Predicted to act upstream of or within regulation of excitatory postsynaptic membrane potential involved in skeletal muscle contraction and regulation of sodium ion transport. Located in membrane. Human ortholog(s) of this gene implicated in myotonic dystrophy type 1. Orthologous to human DMPK (DM1 protein kinase). [provided by Alliance of Genome Resources, Apr 2022]
