fat-5 encodes a delta-9 fatty acid desaturase that is predicted to be mitochondrial; when expressed heterologously in S. cerevisiae, FAT-5 rescues the fatty acid auxotrophy of the yeast delta-9 desaturase mutant ole1.
Predicted to enable iron ion binding activity and stearoyl-CoA 9-desaturase activity. Involved in long-chain fatty acid biosynthetic process and post-embryonic development. Predicted to be located in endoplasmic reticulum membrane. Expressed in intestine and tail. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 79. Is an ortholog of human SCD (stearoyl-CoA desaturase) and SCD5 (stearoyl-CoA desaturase 5).
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.
