Enables scavenger receptor binding activity. Predicted to be involved in several processes, including carnitine transport; positive regulation of protein targeting to membrane; and regulation of ion transport. Predicted to act upstream of or within in utero embryonic development. Located in apical plasma membrane; membrane raft; and microvillus membrane. Orthologous to human PDZK1 (PDZ domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
