wrt-4 encodes a hedgehog-like protein, with (from N- to C-terminus) asignal sequence, a Wart domain, an short region of low-complexitysequence, and a Hint/Hog domain; WRT-4 is expressed strongly inhypodermal syncytia hyp6-hyp10 from 3-fold embryos to adults; theHint/Hog domain is predicted to cut WRT-4 into two halves and thencovalently link cholesterol to the C-terminus of the Wart domain; theWart domain is predicted to form a cysteine-crosslinked protein involvedin intercellular signalling, and it has subtle similarity to theN-terminal Hedge domain of HEDGEHOG proteins; WRT-4 is weakly requiredfor normal molting; WRT-4 is also required for normal adult alaeformation, growth to full size, locomotion, and male tail development;all of these requirements may reflect common defects incholesterol-dependent hedgehog-like signalling or in vesicletrafficking.
Predicted to enable peptidase activity. Acts upstream of or within nematode male tail mating organ morphogenesis. Predicted to be located in cell surface; extracellular region; and plasma membrane. Expressed in hyp10; hyp6; hyp7 syncytium; hyp8; and hyp9. Human ortholog(s) of this gene implicated in several diseases, including Hirschsprung's disease; gastrointestinal system cancer (multiple); and glomerulonephritis (multiple). Is an ortholog of human SHH (sonic hedgehog signaling molecule).

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.
