Summary: Enables lipopolysaccharide immune receptor activity; peptidoglycan binding activity; and peptidoglycan immune receptor activity. Involved in defense response to other organism; regulation of defense response; and regulation of synaptic plasticity. Located in apicolateral plasma membrane; cytoplasmic vesicle; and presynapse. Is expressed in adult Malpighian tubule; embryonic dorsal epidermis; embryonic large intestine; embryonic ventral epidermis; and embryonic/larval lymph gland. Used to study lower respiratory tract disease. [provided by Alliance of Genome Resources, Dec 2024]
