**Background of Recombinant Human YPEL2 Protein**
YPEL2 (Yippee-like 2) is a member of the evolutionarily conserved Yippee protein family, initially identified in *Drosophila* for its role in cell cycle regulation and differentiation. In humans, YPEL2 is a small, nucleus-localized protein encoded by the *YPEL2* gene, located on chromosome 17q21.31. It shares structural homology with other family members, including a conserved cysteine-rich "Yippee" domain implicated in metal ion binding and protein interactions.
Functionally, YPEL2 is linked to cellular senescence, proliferation, and apoptosis. Studies suggest it acts as a stress-inducible protein, modulating pathways like p53 to promote cell cycle arrest or senescence under oxidative or oncogenic stress. Its overexpression inhibits cancer cell growth, while knockdown accelerates proliferation, highlighting its tumor-suppressive potential. Recombinant YPEL2 protein, typically produced in *E. coli* or mammalian systems, serves as a key tool for investigating these mechanisms. Applications include *in vitro* binding assays, signaling pathway analysis, and studies exploring its role in aging, cancer, or neurodegenerative disorders. Despite progress, its precise molecular interactions and therapeutic relevance remain under active exploration, making it a compelling target for biomedical research.
