Recombinant human EPB41L4A protein, also known as erythrocyte membrane protein band 4.1-like 4A, belongs to the conserved FERM (4.1-ezrin-radixin-moesin) domain-containing protein family. It plays critical roles in regulating cell structure, adhesion, and signaling by linking membrane proteins to the cytoskeleton. Structurally, EPB41L4A contains a FERM domain, which mediates interactions with cytoplasmic regions of transmembrane proteins, and a C-terminal domain involved in binding to cytoskeletal components like actin. Studies suggest its involvement in maintaining cellular integrity, polarity, and mechanical stability across tissues.
EPB41L4A has gained attention in cancer research due to its tumor-suppressive properties. Downregulation or loss of EPB41L4A expression correlates with increased tumor progression, metastasis, and poor prognosis in various cancers, including breast, lung, and colorectal cancers. It is thought to inhibit oncogenic pathways by stabilizing cell junctions, suppressing epithelial-mesenchymal transition (EMT), and modulating signal transduction.
Recombinant EPB41L4A protein is typically produced in mammalian systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications and functionality. This recombinant form enables biochemical studies, interaction mapping, and therapeutic exploration, offering potential for developing targeted anticancer strategies or diagnostic biomarkers. Research continues to unravel its broader physiological and pathological significance.
