01

Overview

Protein disulfide isomerase family A member 3 pseudogene 1 (PDIA3P1), also known as GRP58P, is a non-coding pseudogene. Unlike the protein-coding gene PDIA3, which encodes the multifunctional protein disulfide isomerase ERp57/GRP58 (involved in endoplasmic reticulum quality control, chaperone activity, and immune regulation[3]), PDIA3P1 lacks protein-coding capability and does not produce a functional protein. Although it is catalogued in gene databases and sometimes listed in disease association screens, its biological impact (if any) occurs through non-coding RNA effects or sequence homology rather than direct molecular function. It is not considered a therapeutic target, receptor, enzyme, or transporter[4]. Any medically relevant activity is specific to the related protein-coding gene PDIA3, not PDIA3P1.

Other names
GRP58PGlucose regulated protein, 58kDa pseudogene
02

Mechanism of action

None (not a drug target)

03

Biological functions

None (pseudogenes do not produce functional protein; see description for context)
04

Disease associations

Potential association with "Lung Non-Small Cell Carcinoma" (listed as associated disease, but as a pseudogene, clinical significance typically comes from nearby genes or regulatory effects rather than direct function)[4]
05

Safety considerations

None (pseudogene, not a therapeutic target)
06

Interacting drugs

None (no drugs target PDIA3P1 directly; active protein-coding PDIA3 has more relevance as a drug target)
07

Biomarkers

None reported for PDIA3P1 itself
