**Background of PDRG1 Recombinant Protein**
PDRG1 (p53 and DNA damage-regulated gene 1) is a gene regulated by the tumor suppressor protein p53 and cellular stress signals, notably DNA damage. Located on human chromosome 20q11.21. it encodes a 23 kDa protein implicated in diverse cellular processes, including cell cycle regulation, apoptosis, and tumor suppression. PDRG1 expression is induced under genotoxic stress, hypoxia, or oxidative stress, suggesting its role in stress response pathways. Studies link PDRG1 to p53-mediated pathways, where it may act as a downstream effector to modulate cell fate decisions, though its exact molecular mechanisms remain under investigation.
The recombinant PDRG1 protein, produced via *in vitro* expression systems (e.g., *E. coli* or mammalian cells), is a valuable tool for functional studies. It enables researchers to explore PDRG1's interactions with binding partners, such as p53 and HSP90. and its involvement in pathways like the unfolded protein response (UPR) and endoplasmic reticulum (ER) stress. Structural analyses reveal conserved α-helical and coiled-coil domains, hinting at roles in protein-protein interactions or scaffold functions.
Aberrant PDRG1 expression has been observed in cancers, including lung, liver, and colorectal tumors, where it may serve as a biomarker or therapeutic target. Recombinant PDRG1 facilitates *in vitro* assays (e.g., phosphorylation studies, binding kinetics) and *in vivo* models to dissect its dual roles in promoting or suppressing tumorigenesis, depending on cellular context. Additionally, it aids in drug screening to identify compounds modulating PDRG1 activity, with potential implications for cancer therapy. Despite progress, further research is needed to clarify its regulatory networks and therapeutic relevance.
