Enables scavenger receptor activity. Involved in several processes, including cytoskeleton organization; left/right axis specification; and phagocytosis. Located in several cellular components, including phagocytic cup; phagocytic vesicle membrane; and pseudopodium membrane. Expressed in body wall musculature; engulfing cell; hyp7
syncytium; and muscle cell. Human ortholog(s) of this gene implicated in early-onset myopathy-areflexia-respiratory distress-dysphagia syndrome. Is an ortholog of human MEGF10 (multiple EGF like domains 10) and MEGF11 (multiple EGF like domains 11).
