lys-1 encodes a putative lysozyme, whose overexpression increasesresistance to infection by Serratia marcescens; lys-1(RNAi) animals havenormal resistance to S. marcescens, perhaps because of geneticredundancy with the LYS-1 paralogs LYS-2 to -8 and LYS-10; in uninfectedanimals, LYS-1 is expressed in the intestine and in IL1/IL2 neurons,along with a few unidentified head neurons; in intestinal cells, LYS-1localizes to apical vesicles; LYS-1 expression is induced by infectionby Pseudomonas aeruginosa but not S. marcescens; LYS-1 expression ispromoted by DBL-1, TIR-1 and NSY-1, and perhaps also by ELT-2, but notby DAF-16; LYS-1 and its paralogs are more similar to lysozymes from theamoeboid protozoon Entamoeba histolytica than to more familiar ones fromvertebrates.
Involved in defense response to Gram-negative bacterium; defense response to Gram-positive bacterium; and innate immune response. Located in apical part of cell and cytoplasmic vesicle. Expressed in intestine and neurons.
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.
