L1CAM Proteome Profiler Antibody Arrays

The cell adhesion molecule L1 (L1CAM) is an immunoglobulin superfamily adhesion molecule that is critical for neural development. Two alternatively spliced isoforms of L1CAM have been described. The full-length signaling isoform is expressed exclusively in neurons. The second non-neuronal variant lacks a five-residue extracellular sequence and a four residue cytoplasmic sequence that is important in signaling and clathrin-mediated endocytosis.
