General annotation (Comments)

Function

Mediates thiol-dependent retention in the early secretory pathway, forming mixed disulfides with substrate proteins through its conserved CRFS motif. Inhibits the calcium channel activity of ITPR1. May have a role in the control of oxidative protein folding in the endoplasmic reticulum. Required to retain ERO1L and ERO1LB in the endoplasmic reticulum By similarity.

Subunit structure

Forms mixed disulfides with both ERO1L and ERO1LB and cargo folding intermediates By similarity. Directly interacts with ITPR1 in a pH-, redox state- and calcium-dependent manner, but not with ITPR2 or ITPR3. The strength of this interaction inversely correlates with calcium concentration. Ref.4

Subcellular location

Endoplasmic reticulum lumen Ref.4.

Tissue specificity

Widely expressed. Ref.4

Sequence similarities

Contains 1 thioredoxin domain.

Sequence caution

The sequence BAD32251.1 differs from that shown. Reason: Erroneous initiation.
