Synthesis pass · prose summary of the discoveries below

EPB41L3 (protein 4.1B/DAL-1) is a FERM-domain-containing membrane-cytoskeletal adaptor that functions as a tumor suppressor and an organizer of specialized axonal membrane domains. Its FERM domain directly engages transmembrane partners—including TSLC1/CADM1, EGFR, and Caspr/Caspr2—while its C-terminal domain binds β8 integrin and its U2 domain, when membrane-localized, activates a Src–Rac1–JNK growth-suppressive cascade; it inhibits EGFR dimerization/autophosphorylation to dampen MAPK/ERK and PI3K/AKT signaling, induces caspase-8-mediated apoptosis, and maintains E-cadherin expression to oppose epithelial–mesenchymal transition (PMID:31492173, PMID:16420693, PMID:27312663, PMID:16707455). In myelinated neurons, 4.1B is essential for anchoring Caspr at paranodes and Caspr2/Kv1 channels at juxtaparanodes, thereby establishing the membrane barriers that compartmentalize ion channels around nodes of Ranvier, as demonstrated by loss of these domains in 4.1B-null mice (PMID:20164332, PMID:21632923). A 200 kDa isoform localizes to the Golgi apparatus and is required for trafficking of Na⁺/K⁺-ATPase and tight-junction proteins to the plasma membrane (PMID:19299464).
