**Background of Recombinant Human PEG10 Protein**
PEG10 (Paternally Expressed Gene 10) is a retrotransposon-derived protein encoded by a retrotransposon-like gene that was co-opted during mammalian evolution. Initially identified for its role in placental development, PEG10 is imprinted and paternally expressed, contributing to embryogenesis and tissue homeostasis. Structurally, PEG10 contains conserved domains, including a “RHO” domain similar to retroviral gag-pol proteins, enabling self-assembly and potential involvement in cellular processes like vesicle formation or RNA regulation.
Dysregulation of PEG10 is strongly linked to cancer progression. It is overexpressed in multiple malignancies (e.g., liver, lung, prostate cancers), promoting cell proliferation, migration, and anti-apoptotic signaling. Its oncogenic role may involve interactions with pathways like Wnt/β-catenin or MAPK.
Recombinant human PEG10 protein, produced via genetic engineering (e.g., bacterial or mammalian expression systems), retains functional domains for *in vitro* studies. Researchers use it to investigate PEG10's molecular mechanisms, its role in disease models, and therapeutic targeting. Its application spans biomarker discovery, drug screening, and understanding retrotransposon-derived gene functions in health and disease. Current research focuses on elucidating PEG10’s structural dynamics and its potential as a therapeutic target, particularly in cancers driven by its aberrant expression.
