**Background of TDGF1P3 Recombinant Protein**
TDGF1P3 (Teratocarcinoma-Derived Growth Factor 1 Pseudogene 3) is a pseudogene derived from the TDGF1 gene, which encodes a member of the epidermal growth factor (EGF)-Cripto-1/FRL-1/Cryptic (CFC) protein family. While pseudogenes are typically non-functional due to mutations disrupting their coding potential, emerging studies suggest that TDGF1P3 may retain regulatory roles, particularly in modulating gene expression at the RNA level. It shares high sequence homology with TDGF1 (also known as Cripto-1), a key protein involved in embryonic development, stem cell maintenance, and oncogenesis through pathways like Wnt/β-catenin and Notch signaling.
The recombinant TDGF1P3 protein is produced using biotechnological methods, such as expression in bacterial or mammalian systems, followed by purification to ensure homogeneity. This engineered protein enables researchers to study its potential biological activities, interactions, and mechanisms independent of its pseudogene classification. Although TDGF1P3’s functional significance remains less characterized compared to TDGF1. evidence suggests it may act as a competitive endogenous RNA (ceRNA) or interact with signaling molecules, influencing cellular processes like proliferation, differentiation, or tumor progression.
Interest in TDGF1P3 has grown due to its dysregulation in cancers, including gastric, breast, and colorectal cancers, where it may serve as a biomarker or therapeutic target. Recombinant TDGF1P3 facilitates investigations into its role in cancer biology, stem cell regulation, and developmental pathways, bridging gaps between pseudogene biology and disease mechanisms. Further research is needed to elucidate its precise functions and translational potential in biomedicine.
