Summary: Enables mRNA binding activity and structural molecule activity. Involved in several processes, including behavioral response to starvation; mRNA transport; and vesicle-mediated intercellular transport. Located in several cellular components, including postsynapse of neuromuscular junction; sarcomere; and virus-like capsid. Is expressed in several structures, including adult antennal lobe; adult brain; adult head; ganglia; and pars intercerebralis. [provided by Alliance of Genome Resources, Dec 2024]
