hyl-2 encodes a predicted transmembrane protein orthologous to Saccharomyces cerevisiae Lag1p (longevity assurance gene), a protein preferentially expressed in young yeasts; by homology, HYL-2 is predicted to have several possible functions, including regulation of lipid, particularly ceramide, biosynthesis, regulation of lipid transport, and regulation of protein translocation in the endoplasmic reticulum ; however, as loss of hyl-2 activity via RNA-mediated interference (RNAi) does not result in any obvious abnormalities, the precise role of hyl-2 in C. elegans development and/or behavior is not yet known.
Predicted to enable sphingosine N-acyltransferase activity. Predicted to be involved in ceramide biosynthetic process. Predicted to be located in membrane. Expressed in head; hypodermis; intestine; tail; and terminal bulb. Human ortholog(s) of this gene implicated in autosomal recessive congenital ichthyosis 9. Is an ortholog of human CERS6 (ceramide synthase 6).
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.
