The T05H4.5 gene encodes an ortholog of the human gene NADH-CYTOCHROME B5 REDUCTASE (DIA1), which when mutated leads to methemoglobinemia (OMIM:250800).
Predicted to enable FAD binding activity. Predicted to be located in mitochondrion. Human ortholog(s) of this gene implicated in estrogen-receptor negative breast cancer and methemoglobinemia. Is an ortholog of human CYB5R1 (cytochrome b5 reductase 1); CYB5R2 (cytochrome b5 reductase 2); and CYB5R3 (cytochrome b5 reductase 3).
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.
