Humans " are not believed to have a magnetic sense ", but humans do have a cryptochrome ( a flavoprotein, CRY2 ) in the retina which has a light-dependent magnetosensitivity.

The enzyme belongs to the group of oxidoreductases according EC classification and is dependent on FAD as cofactor, thus it was classified as an external flavoprotein monooxygenase ( designated as type E ).
The number of flavin-dependent protein encoded genes in the genome ( the flavoproteome ) is species dependent and can range from 0.1 %-3.5 %, with humans having 90 flavoprotein encoded genes.

This gene encodes the penultimate enzyme of heme biosynthesis, which catalyzes the 6-electron oxidation of protoporphyrinogen IX to form protoporphyrin IX . This protein is a flavoprotein associated with the outer surface of the inner mitochondrial membrane.
40.
The FMN-binding domain is similar to the structure of FMN-containing protein flavodoxin, whereas the FAD-binding domain and NADPH-binding domains are similar to those of flavoprotein ferredoxin-NADP + reductase ( FNR ).
