| Buffer | The default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol if the delivery form is liquid. The lyophilization buffer is Tris/PBS-based buffer, 6% Trehalose, pH 8.0 if the delivery form is lyophilized powder. Please contact us if you have any special requirment. |
| Reconstitution | Please reconstitute protein in deionized sterile water and we recommend that briefly centrifuge thevial prior to opening the vial .We recommend aliquot for long-term storage at -20℃/-80℃. |
Background
| Relevance | This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins. Inside the cell, seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations, functions as a chaperone that inhibits aggregation of misfolded proteins. At low concentrations, facilitates aggregation (anti-chaperone activity). May be involved with other chaperones in the structural modification of the TG precursor in hormone biogenesis. Also acts a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP. Receptor for LGALS9; the interaction retains P4HB at the cell surface of Th2 T helper cells, increasing disulfide reductase activity at the plasma membrane, altering the plasma membrane redox state and enhancing cell migration. |
