Pigment precursor permease/Protein ATP-binding cassette sub-family G (IPR005284)
Short name: Pigment_permease/Abcg
Overlapping homologous superfamilies
- Pigment precursor permease/Protein ATP-binding cassette sub-family G (IPR005284)
- ABC transporter, G1 (IPR020064)
This family includes pigment precursor permeases (protein white, brown and scarlet) from flies and ATP-binding cassette sub-family G member 1 (ABCG1) from mammals.
The fly pigment precursor permeases are membrane-spanning proteins necessary for the transport of pigment precursor into pigment cells responsible for eye colour. White protein dimerises with brown protein for the transport of guanine and with scarlet protein for the transport of tryptophan [PMID: 3149712].
