Predicted to enable retinol transmembrane transporter activity. Acts upstream of or within positive regulation of receptor signaling pathway via JAK-STAT and retinol transport. Located in plasma membrane. Is expressed in several structures, including central nervous system; embryo mesenchyme; extraembryonic component; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in syndromic microphthalmia 9. Orthologous to human STRA6 (signaling receptor and transporter of retinol STRA6).
