Fbxl20 - F-box and leucine-rich repeat protein 20

Involved in regulation of protein catabolic process at presynapse, modulating synaptic transmission and regulation of synaptic vesicle exocytosis. Acts upstream of or within behavioral fear response. Located in Schaffer collateral - CA1 synapse. Is active in glutamatergic synapse. Is expressed in several structures, including adrenal gland; brain; genitourinary system; gut; and respiratory system. Orthologous to human FBXL20 (F-box and leucine rich repeat protein 20).
