Predicted to enable transforming growth factor beta binding activity. Predicted to be involved in several processes, including animal organ development; cholesterol efflux; and cholesterol homeostasis. Predicted to act upstream of or within several processes, including ciliary body morphogenesis; negative regulation of Wnt signaling pathway; and telencephalon development. Predicted to be active in extracellular matrix; extracellular space; and plasma membrane. Orthologous to human TSKU (tsukushi, small leucine rich proteoglycan).
