Preparation and Storage

Background: gp96/HSP90B1

Glycoprotein 96 (gp96; also endoplasmin, GRP-94, TRA1 and HSP90B1) is a 94-100 kDa member of the HSP 90 family of proteins. gp96 is a ubiquitously-expressed ER resident protein that is found in a preformed complex with BiP, CaBP1 and UDP-glucosyltransferase. This is a chaperone complex that binds unfolded protein substrates. When folded properly, the substrate is forwarded to calnexin-containing chaperone complexes that promote its maturation. gp96 clients are restricted and include disulfide-bonded integrins, TLRs, LDLR and CD180. Within the complex, gp96 exists as a disulfide-linked homodimer that may form higher-order oligomers. gp96 also appears on the cell surface and may serve as a receptor for bacteria. Mature human gp96 is a 782 amino acid (aa) membrane-associated protein
(aa 22-803). It is not a transmembrane protein but utilizes an ER retention signal (aa 800-803) to interact with the ER membrane. The molecule possesses a
HATPase-C like region (aa 98-219) plus multiple ATP binding and two utilized phosphorylation sites. Over aa 503-660, human gp96 shares 98% aa sequence identity with mouse gp96.
