Enables peptide transmembrane transporter activity. Acts upstream of or within several processes, including determination of left/right symmetry; patched ligand maturation; and smoothened signaling pathway. Predicted to be located in membrane. Predicted to be integral component of membrane. Is expressed in several structures, including embryo ectoderm; embryo mesenchyme; foot bone; notochord; and palatal shelf. Orthologous to human DISP1 (dispatched RND transporter family member 1). [provided by Alliance of Genome Resources, Apr 2022]
