Description

ptr-1 encodes an ortholog of Drosophila and human PTCHD3, which defines one of seven paralogous families of sterol sensing domain (SSD) proteins; individually, PTR-1 is weakly required for normal molting from L4 to adult stages; however, PTR-1, in conjunction with either PTR-16 alone or with PTR-6 and PTR-10, is strongly required for both molting and viability, with double ptr-1/-16 or triple ptr-1/-6/-10 RNAi animals showing pronounced molting defects and lethality; PTR-1 is also required for normal adult alae formation, growth to full size, locomotion, and male tail development.
