Transporter, which promotes the endocytosis-mediated degradation of hedgehog-related proteins such as grl-7 in order to establish the capacity of progenitor cells to maintain quiescence in arrested L1 stage larvae. Localizes to the apical cell membrane during the 3-fold stage during embryogenesis. First expressed in hypodermal, seam, and P cells at the 3-fold stage during embryogenesis (at protein level) (PubMed:33872306). During late embryogenesis, expressed in hypodermal and P neural progenitor cells (at protein level) (PubMed:33872306). At the late L1 larval stage, expressed in the descendants of P cells, rectal epithelial F, K, and U cells and seam cells (at protein level) (PubMed:33872306). Degraded in a lysosome-dependent manner before hatching. Belongs to the patched family.
