**Recombinant Human PPPDE1 Protein: Background**
PPPDE1 (Protein Phosphatase Domain Containing 1), also known as threonine tyrosine phosphatase (TYPP), is a member of the protein phosphatase family characterized by a conserved phosphatase domain. This enzyme plays a regulatory role in cellular processes, including endoplasmic reticulum (ER) stress response, apoptosis, and protein quality control. It contains a thioredoxin-like fold domain, which is critical for its enzymatic activity and interaction with substrates.
PPPDE1 is implicated in modulating signaling pathways such as the unfolded protein response (UPR) and NF-κB signaling, linking it to diseases like cancer, neurodegenerative disorders, and metabolic syndromes. Its expression is tissue-specific, with higher levels observed in the liver, kidney, and brain. Dysregulation of PPPDE1 has been associated with tumor progression, where it may act as either an oncogene or tumor suppressor depending on cellular context.
Recombinant human PPPDE1 protein is typically produced in *E. coli* or mammalian expression systems, enabling functional studies of its phosphatase activity, substrate specificity, and structural features. It serves as a key tool for investigating molecular mechanisms underlying ER stress-related pathologies and screening potential therapeutic agents targeting PPPDE1-associated pathways. Recent studies also explore its role in viral infections and immune regulation, highlighting its versatility as a research target.
The development of recombinant PPPDE1 has advanced both basic and translational research, offering insights into its dual roles in cellular homeostasis and disease, with potential applications in drug discovery and biomarker development.
