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

HOMOLOGY

Homologene

FAMILY

SIL1 family

CATEGORY

chaperone/stress , regulatory

SUBCELLULAR LOCALIZATION	plasma membrane

	intracellular,cytoplasm,organelle,Golgi
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

protein

interacts with the ATPase domain of BIP (HSPA5), cochaperone of HSPA5(first nucleotide exchange factor for HSPA5, binding to its ATPase domain in the ER lumen)
