PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • an N-terminal ER targeting sequence
  • 2 putative N-glycosylation sites
  • a C-terminal ER retention signal, and very C-terminal AAs of SIL1 play a role potential in its structural integrity rather than its localization
  • conjugated GlycoP

    text
  • wild-type protein could be detected in the Golgi as well as the ER
  • basic FUNCTION
  • ER protein, nucleotide exchange factor that regulates the ATPase activity of HSPA5
  • adenine nucleotide exchange factor of the essential ER lumen chaperone HSPA5 that senses ER stress and is involved in protein folding
  • facilitates the release of HSPA5 from unfolded protein substrates, enabling the subsequent folding and transport of the protein
