grd-3 encodes a hedgehog-like protein, with an N-terminal signalsequence and a C-terminal Ground domain; GRD-3 is expressed in adultanterior and posterior seam cells, overlapping GRD-5 expression; GRD-3is also strongly expressed upon infection with the gram-negativebacterium Serratia marcescens, indicating that GRD-3 may be part of C.elegans' innate immunity response; the Ground domain is predicted toform a cysteine-crosslinked protein acting as an intercellular signal,and it has subtle similarity to the N-terminal Hedge domain of HEDGEHOGproteins; GRD-3 is weakly required for normal molting; GRD-3 is alsorequired for normal growth to full size and locomotion; all of theserequirements may reflect common defects in cholesterol-dependenthedgehog-like signalling or in vesicle trafficking.
Predicted to enable signaling receptor binding activity. Involved in defense response to Gram-negative bacterium. Predicted to be located in extracellular region.
yk66e9 spans only grd-3, which contains just ground domain. grd-3, grd-10, and grd-13 form a cluster, grd-3 and grd-13 are paralogous to the grd-4 and grd-14 cluster.
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.
