Using in silico analyses and mutational studies we found that the C-terminal sequences of Gap1, Bap2, Hip1, Tat1, Tat2, Mmp1, Sam3, Agp1, and Gnp1 are about 50 residues long, associate with the Plasma Membrane , and have features that discriminate them from the termini of organellar amino acid transporters

Fifteen amino acid residues in Tat2 transmembrane domains 1, -3, -5, -8, and -10 are responsible for tryptophan uptake.
Title: Structural and functional implications of the yeast high-affinity tryptophan permease Tat2.
Data show that tryptophan transport is increased in pdr5Delta/yor1 strains and reduced in rsb1Delta cells, and the localization and vacuolar degradation of Tat2 were affected in these genetic backgrounds.

Sna3 is a potential competitor of Bul1 for the Rsp5 WW domain affecting degradation of tryptophan permease Tat2.
Title: Overexpression of Sna3 stabilizes tryptophan permease Tat2, potentially competing for the WW domain of Rsp5 ubiquitin ligase with its binding protein Bul1.
Here, it is shown that the deletion in ERG2, which encodes sterol C8-C7 isomerase (the next enzymatic step after Erg6), promotes the vacuolar degradation of Tat2.
