ptc-3 encodes an ortholog of Drosophila PATCHED (PTC) and human PTCH(OMIM:601309, mutated in basal cell nevus syndrome), which defines oneof seven paralogous families of sterol sensing domain (SSD) proteins;PTC-3 is strongly required for normal molting from L1 to L3 larvalstages; PTC-3 is also required for normal growth to full size and forviability.
Predicted to enable hedgehog family protein binding activity; hedgehog receptor activity; and smoothened binding activity. Involved in molting cycle. Located in apical plasma membrane and cytoplasmic vesicle. Expressed in several structures, including CEP; cloaca; egg-laying apparatus; excretory duct; and preanal ganglion. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); colorectal adenoma; and holoprosencephaly 7. Is an ortholog of human PTCH1 (patched 1) and PTCH2 (patched 2).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
