Sequence Info : Partial
Tag Info : N-terminal 6xHis-tagged
Theoretical MW : 56.6 kDa
Storage Buffer : Lyophilized from a 0.2 µm filtered PBS, pH 7.0
Endotoxin Level : Less than 1.0 EU/µg as determined by LAL method.-
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.
Storage : Short term: -20°C; Long term: -80°C. Minimize freeze and thaw cycles.
Research Area : Signal Transduction
Restriction : For Research Use Only. Not for use in diagnostic procedures, drug use, or for administration to humans or animals.
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
