BLT101 of Lophopyrum elongatum (P68178)
*9.B.12.1.2









Membrane peptide of 55 aas, plasma membrane proteolipid 3, Pmp3/Sna1. Plays a role in the regulation of membrane potential, possible by mediating a proton leak (Navarre and Goffeau 2000).

Pmp3 of Rhizobus delemar
*9.B.12.3.1









Uncharacterized ORF, Sna3 (YJL151c).  Targeting to the endosomal pathway depends on its interaction with Rsp5p, and multivesicular body sorting depends on ubiquitylation (Stawiecka-Mirota et al. 2007).

Sna3 of Saccharomyces cerevisiae
*9.B.12.3.2









Vacuolar Sna4 of 140 aas with two N-terminal TMSs.  It is transported to the vauolar membrane via the alkaline phosphatase (ALP) pathway which bypasses the multivesicular bodies (MVBs) (Pokrzywa et al. 2009).

Sna4 of Saccharomyces cerevisiae
*9.B.12.3.3









Sna2 of 79 aas.  Two tyroline-based sorting motifs are required for proper ER exit and vacuolar targeting (Renard et al. 2010).
