**Background of P4HB Antibody**
The P4HB (Prolyl 4-Hydroxylase Beta Subunit) antibody targets the P4HB protein, a critical component of the prolyl 4-hydroxylase complex responsible for post-translational modification of collagen. P4HB, also known as Protein Disulfide Isomerase A1 (PDIA1), functions as a molecular chaperone and enzyme in the endoplasmic reticulum (ER), facilitating proper protein folding by catalyzing disulfide bond formation and isomerization. It plays a vital role in collagen biosynthesis by hydroxylating proline residues, essential for collagen stability and extracellular matrix integrity.
P4HB is implicated in various physiological and pathological processes, including tissue repair, cancer progression, and ER stress response. Overexpression of P4HB has been observed in cancers such as glioblastoma and hepatocellular carcinoma, correlating with tumor aggressiveness and poor prognosis. It is also linked to fibrotic diseases and neurodegenerative disorders like Alzheimer’s, where ER stress and protein misfolding are prominent.
Antibodies against P4HB are widely used in research to study protein folding mechanisms, ER stress pathways, and collagen-related disorders. They serve as tools in Western blotting, immunohistochemistry, and immunofluorescence to assess P4HB expression and localization. Additionally, P4HB antibodies have potential diagnostic and therapeutic applications, particularly in targeting cancer cells or modulating ER stress in disease models. Understanding P4HB's roles continues to drive investigations into its utility as a biomarker or therapeutic target.
