P4hb Gene Summary [Rat]
Enables enzyme binding activity and protein disulfide isomerase activity. Predicted to be involved in several processes, including positive regulation of substrate adhesion-dependent cell spreading; positive regulation of viral entry into host cell; and protein maturation. Predicted to act upstream of with a positive effect on endoplasmic reticulum to Golgi vesicle-mediated transport. Predicted to act upstream of or within cellular response to interleukin-7 and peptidyl-proline hydroxylation to 4-hydroxy-L-proline. Predicted to be located in several cellular components, including cytosol; endoplasmic reticulum-Golgi intermediate compartment; and lamellipodium. Predicted to be part of endoplasmic reticulum chaperone complex and procollagen-proline 4-dioxygenase complex. Predicted to be active in endoplasmic reticulum lumen and external side of plasma membrane. Human ortholog(s) of this gene implicated in Cole-Carpenter syndrome. Orthologous to human P4HB (prolyl 4-hydroxylase subunit beta). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat P4hb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
