description: Ykl077w/Psg1 (Pma1 Stabilization in the Golgi) physically interacts with Exp1 (for ER eXport
  of Pma1). Psg1 can be found in the Golgi and coat protein I (COPI) vesicles but does not directly bind
  Pma1. Loss of Psg1 causes enhanced degradation of Pma1 in the vacuole. Psg1 is 392aa protein with a
  predicted signal sequence at its N-terminus and a single TMD near the C-terminus. The short cytosolic
  region bears 2 putative retrieval motifs KRR and KKxxKxx. It was previously shown to be cleaved by the
  Ca+ dependent serine protease, Kex2 [[cite:PUB00093685]].
