DKK3 (Dickkopf-related protein 3) is a secreted glycoprotein belonging to the Dickkopf family, known for its regulatory role in the Wnt signaling pathway. Unlike other DKK members (e.g., DKK1) that primarily inhibit canonical Wnt/β-catenin signaling, DKK3 exhibits a more complex, context-dependent interaction with Wnt and other pathways, including TGF-β and PI3K/AKT. Structurally, it contains two conserved cysteine-rich domains (CRD1 and CRD2) stabilized by disulfide bonds, critical for its stability and receptor binding.
DKK3 is broadly expressed in embryonic tissues and certain adult organs (e.g., kidneys, heart, and blood vessels), playing roles in tissue homeostasis, fibrosis regulation, and tumor suppression. It is implicated in modulating cell proliferation, apoptosis, and differentiation. In cancer, DKK3 often acts as a tumor suppressor, with its downregulation linked to tumor progression via epigenetic silencing or promoter hypermethylation. Conversely, elevated DKK3 in fibrotic diseases (e.g., liver or kidney fibrosis) suggests a pro-fibrotic role, highlighting its dual regulatory functions.
Recombinant DKK3 protein, produced using mammalian expression systems (e.g., HEK293 cells) to ensure proper post-translational modifications, serves as a key tool for studying DKK3-mediated signaling mechanisms. Its therapeutic potential is being explored in regenerative medicine, anti-fibrotic therapies, and cancer treatment. Challenges in production include maintaining structural integrity and bioactivity, necessitating stringent quality control. Recent studies also investigate its utility as a biomarker for diseases like chronic kidney disease and certain cancers, underscoring its clinical relevance.
