Enables scavenger receptor activity. Acts upstream of or within heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules. Predicted to be located in membrane. Predicted to be integral component of membrane. Is expressed in brain; metanephros; skin; thoracic segment skeleton; and trachea. Human ortholog(s) of this gene implicated in Van den Ende-Gupta syndrome. Orthologous to human SCARF2 (scavenger receptor class F member 2). [provided by Alliance of Genome Resources, Apr 2022]
