GENE INFORMATION
Gene name	P4HB (HGNC Symbol)
Synonyms	DSI, ERBA2L, GIT, P4Hbeta, PDI, PDIA1, PO4DB, PO4HB, PROHB
Description	Prolyl 4-hydroxylase, beta polypeptide (HGNC Symbol)
Entrez gene summary	This gene encodes the beta subunit of prolyl 4-hydroxylase, a highly abundant multifunctional enzyme that belongs to the protein disulfide isomerase family. When present as a tetramer consisting of two alpha and two beta subunits, this enzyme is involved in hydroxylation of prolyl residues in preprocollagen. This enzyme is also a disulfide isomerase containing two thioredoxin domains that catalyze the formation, breakage and rearrangement of disulfide bonds. Other known functions include its ability to act as a chaperone that inhibits aggregation of misfolded proteins in a concentration-dependent manner, its ability to bind thyroid hormone, its role in both the influx and efflux of S-nitrosothiol-bound nitric oxide, and its function as a subunit of the microsomal triglyceride transfer protein complex.
