Predicted to enable ATP binding activity. Predicted to contribute to actin filament binding activity and microfilament motor activity. Predicted to be involved in several processes, including mitochondrion morphogenesis; neuronal action potential; and sensory perception of sound. Predicted to act upstream of or within actin filament-based movement. Predicted to be located in several cellular components, including brush border; myosin II filament; and stress fiber. Predicted to be part of myosin II complex. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 4A and sensorineural hearing loss. Orthologous to human MYH14 (myosin heavy chain 14). [provided by Alliance of Genome Resources, Apr 2022]
