motor protein


Also found in: Dictionary, Wikipedia.

motor protein

n.
A protein, such as myosin, that converts chemical energy into mechanical energy, generating force that powers cell movement and the transport of substances and organelles within cells.

motor protein

protein that moves along a surface, propelled by the energy of adenosine triphosphate hydrolysis.

IMMT

A gene on chromosome 11p15.5 that encodes mitofilin (mitochondrial inner membrane protein), an ATP-driven motor protein primarily expressed in muscle, which interacts with cytoskeletal components.
