Rabbit anti-Human ERO1B Polyclonal Antibody

Uniprot Id

Q86YB8

Target Species

Human

Target Name

ERO1B

Target Full Name

ERO1-like protein beta

Target 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.

Target Subcellular Location

Endoplasmic reticulum membrane; Peripheral membrane protein; Lumenal side. Note=The association with ERP44 may be essential for its retention in the endoplasmic reticulum.

Target Protein Families

EROs family

Target Tissue Specificity

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 enz
