What's a GeneRIF?
  1. Sho1-Opy2 interaction enhances the activation of Pbs2 by Ste11, but not Hog1 by Pbs2. Chemical crosslinking and mutational analyses revealed that the cytoplasmic ends of Sho1 TM1 and Opy2 TM also interact with each other, defining the Sho1-Opy2 binding site 2 (BS2).

  2. The extracellular cysteine-rich domain of the transmembrane-anchor protein Opy2 binds to the Hkr1-Msb2 homology domain of the putative osmosensor Msb2 and the formation of the Opy2-Msb2 complex is essential for osmotic activation of Hog1.

NP_015400.1
  • Integral membrane protein that acts as a membrane anchor for Ste50p; involved in the signaling branch of the high-osmolarity glycerol (HOG) pathway and as a regulator of the filamentous growth pathway; overproduction blocks cell cycle arrest in the presence of mating pheromone; relocalizes from vacuole to plasma membrane upon DNA replication stress
