Anti-L1CAM/CD171 Antibody, clone S10.33

Neural cell adhesion molecule L1 (UniProt: P11627; also known as N-CAM-L1, NCAM-L1, CD171) is encoded by the L1cam (also known as Caml 1) gene (Gene ID: 16728) in murine species. L1CAM is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 20-1123), a transmembrane domain (aa 1124-1146), and a cytoplasmic domain (aa 1147-1260). The large extracellular domain contains six Ig-like C2 type domains and five fibronectin type III repeats. It serves as a cell recognition molecule within the nervous system that plays a critical role in multiple processes, including neuronal migration, axonal growth and fasciculation, and synaptogenesis during brain development. In the mature brain, it plays a role in the dynamics of neuronal structure and function, including synaptic plasticity. Its expression is also observed in tumor vasculature. Tumor-bearing mice that lack L1CAM exhibit reduced angiogenesis and improved vascular stabilization that leads to reduced tumor growth and metastasis. These effects have been attributed to L1CAM-induced IL-6-mediated STAT3 phosphorylation and inhibition of IL-6/JAK/STAT signaling axis that prevents endothelial cell proliferation and migration.
