grd-4 encodes a hedgehog-like protein, with an N-terminal signalsequence and a C-terminal Ground domain; the Ground domain is predictedto form a cysteine-crosslinked protein involved in intercellularsignalling, and it has subtle similarity to the N-terminal Hedge domainof HEDGEHOG proteins; GRD-4 is weakly required for normal molting; GRD-4is also required for normal adult alae formation, growth to full size,and locomotion; all of these requirements may reflect common defects incholesterol-dependent hedgehog-like signalling or in vesicletrafficking.
Enriched in RME; dopaminergic neurons; and hypodermis based on tiling array; RNA-seq; and single-cell RNA-seq studies. Is affected by several genes including daf-16; daf-2; and skn-1 based on microarray; tiling array; and RNA-seq studies. Is affected by twenty-three chemicals including cholesterol; lathosterol; and methylmercuric chloride based on microarray and RNA-seq studies. Is predicted to encode a protein with the following domain: Ground-like domain.
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.
