Predicted to enable carbohydrate binding activity and pattern recognition receptor activity. Predicted to be involved in immune response. Predicted to be located in extracellular region. Predicted to be active in external side of plasma membrane. Is expressed in embryonic proventriculus and embryonic/larval midgut. Human ortholog(s) of this gene implicated in 3MC syndrome 3; asthma; lung disease (multiple); respiratory syncytial virus infectious disease; and rhinitis. Orthologous to several human genes including COLEC10 (collectin subfamily member 10); SFTPA1 (surfactant protein A1); and SFTPA2 (surfactant protein A2).
