Atypical Solute Carrier Families (Atypical SLCs) are novel plausible secondary active or facilitative transporter proteins that share ancestral background with the known solute carrier families (SLCs).
[1][2] Most atypical SLCs are families within the major facilitator superfamily (MFS).
[3] These atypical SLCs are plausible secondary active or facilitative transporter proteins that share ancestry with the known solute carriers.
[1] ATMFs are categorised based on their sequence similarity and phylogenetic closeness.
All these are atypical SLCs found within the Major facilitator superfamily.
