Podocalyxin-like protein 2 (PODXL2) is a transmembrane glycoprotein belonging to the podocalyxin family, which shares structural homology with CD34 and endoglycan. It is characterized by a heavily glycosylated extracellular domain, O-glycosylation sites, a single-pass transmembrane region, and a cytoplasmic tail. Primarily expressed in vascular endothelial cells, certain epithelial tissues, and tumors, PODXL2 plays a role in regulating cell adhesion, migration, and polarity through interactions with cytoskeletal components. Its extracellular domain mediates selective homophilic or heterophilic binding to other podocalyxin family members or cell-surface receptors, influencing cell-cell communication. Dysregulation of PODXL2 has been linked to cancer progression, particularly in enhancing metastatic potential by promoting epithelial-mesenchymal transition (EMT) and angiogenesis. Overexpression is observed in aggressive cancers like colorectal, breast, and ovarian carcinomas, correlating with poor prognosis. Recombinant human PODXL2 protein, typically produced in mammalian or insect expression systems with tags like His or Fc for purification, serves as a critical tool for functional studies, antibody development, and screening therapeutic agents targeting its oncogenic signaling. Current research explores its dual role as a potential diagnostic biomarker and therapeutic target in precision oncology.
