**Background of Recombinant Human EPB41L3 Protein**
EPB41L3 (Erythrocyte Membrane Protein Band 4.1 Like 3), also known as DAL-1 (Differentially Expressed in Adenocarcinoma of the Lung), is a member of the protein 4.1 superfamily, which plays critical roles in linking membrane proteins to the cytoskeleton and maintaining cellular structural integrity. This tumor suppressor protein is encoded by the *EPB41L3* gene and is characterized by a conserved FERM (Four-point-one, Ezrin, Radixin, Moesin) domain that mediates interactions with membrane-associated proteins and signaling molecules.
EPB41L3 regulates cell adhesion, proliferation, and apoptosis by stabilizing membrane-cytoskeleton connections and modulating signaling pathways, such as the Hippo and Wnt cascades. Its expression is frequently downregulated in various cancers (e.g., lung, breast, prostate) due to promoter hypermethylation, correlating with tumor progression, metastasis, and poor prognosis.
Recombinant human EPB41L3 protein is produced using expression systems (e.g., *E. coli* or mammalian cells) to enable functional studies. It serves as a vital tool for investigating molecular mechanisms underlying tumor suppression, epithelial-mesenchymal transition (EMT), and cytoskeletal dynamics. Researchers utilize it in *in vitro* assays, structural analyses, and therapeutic target validation, aiming to develop diagnostic biomarkers or anticancer strategies targeting EPB41L3-related pathways.
