Enables ferritin receptor activity. Involved in several processes, including cellular iron ion homeostasis; iron ion transmembrane transport; and protein homotrimerization. Acts upstream of or within cellular response to heat. Located in cell surface. Is integral component of plasma membrane. Is expressed in several structures, including eye; gonad; heart; spinal cord; and vertebral pre-cartilage condensation. Orthologous to human SCARA5 (scavenger receptor class A member 5).
