|Application ||WB, IHC-P, FC, E|
|Calculated MW||53543 Da|
|Antigen Region||266-293 aa|
|Other Names||ERO1-like protein beta, ERO1-L-beta, 184-, Endoplasmic reticulum oxidoreductin-1-like protein B, Oxidoreductin-1-L-beta, ERO1LB|
|Target/Specificity||This ERO1LB antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 266-293 amino acids from the C-terminal region of human ERO1LB.|
|Format||Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.|
|Storage||Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||ERO1LB Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Oxidoreductase involved in disulfide bond formation in the endoplasmic reticulum. Efficiently reoxidizes P4HB/PDI, the enzyme catalyzing protein disulfide formation, in order to allow P4HB to sustain additional rounds of disulfide formation. Other protein disulfide isomerase family members can also be reoxidized, but at lower rates compared to P4HB, including PDIA2 (50% of P4HB reoxidation rate), as well as PDIA3, PDIA4, PDIA6 and NXNDC12 (<10%). Following P4HB reoxidation, passes its electrons to molecular oxygen via FAD, leading to the production of reactive oxygen species (ROS) in the cell. May be involved in oxidative proinsulin folding in pancreatic cells, hence may play a role in glucose homeostasis.|
|Cellular Location||Endoplasmic reticulum membrane; Peripheral membrane protein; Lumenal side. Note=The association with ERP44 may be essential for its retention in the endoplasmic reticulum|
|Tissue Location||Highly expressed in the digestive tract, including the duodenum and lower digestive tract. In the stomach, highly expressed in enzyme-producing chief cells (at protein level). In the pancreas, expressed in islets of Langerhans and, at lower levels, in enzyme-secreting cells (at protein level) Detected at low level in many other tissues|

ERO1LB is essential oxidoreductase that oxidizes proteins in the endoplasmic reticulum to produce disulfide bonds. ERO1LB acts by oxidizing directly P4HB/PDI isomerase through a direct disulfide exchange. ERO1LB does not act as a direct oxidant of folding substrate, but relies on P4HB/PDI to transfer oxidizing equivalent.
