Protein Description:Partial
Tag Info:N-terminal 6xHis-tagged
Mol. Weight:56.6 kDa
Biological_Activity:Thiol Protein Reductase Activity is 0.001 ?650nm/ min-2, determined by measuring the turbidity increase at 650 nm due to insulin reduction.The activity is expressed as the ratio of the slope of a linear part of the turbidity curve to the lag time.
Purity:>95% as determined by SDS-PAGE and HPLC.
Endotoxin:Less than 1.0 EU/µg as determined by LAL method.
Form:Lyophilized powder
Buffer:Lyophilized from a 0.2 µm filtered PBS, pH 7.0
Reconstitution:We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.
Alternative Name/ Alias:PDI, Cellular thyroid hormone-binding protein, Prolyl 4-hydroxylase subunit beta, p55,
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. {ECO:0000269|PubMed:10636893, ECO:0000269|PubMed:12485997}.

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
