Sugar/inositol transporter (IPR003663)

Short name: Sugar/inositol_transpt

Overlapping homologous superfamilies

Family relationships


The sugar transporters belong to a superfamily of membrane proteins responsible for the binding and transport of various carbohydrates, organic alcohols, and acids in a wide range of prokaryotic and eukaryotic organisms [PMID: 3839598]. These integral membrane proteins are predicted to comprise twelve membrane spanning domains. It is likely that the transporters have evolved from an ancient protein present in living organisms before the divergence into prokaryotes and eukaryotes [PMID: 3543693]. In mammals, these proteins are expressed in a number of organs [PMID: 3170580].

This family includes sugar transporters and the myo-inositol transporters.
