General description

Anti-L1CAM antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the hybridoma UJ127.11 produced by the fusion of mouse myeloma cells (P3- X63-Ag8-653 cells) and splenocytes from mice immunized with human fetal brain. L1 cell adhesion molecule (L1CAM) protein belongs to the family of cell adhesion molecules (CAM).

The gene L1CAM (L1 cell adhesion molecule) encodes a member of the immunoglobulin supergene family. The encoded protein contains a cytoplasmic intracellular domain, one single-pass transmembrane region and an extracellular domain containing six immunoglobulin- (Ig) and five fibronectin (Fn) III-like motifs. The gene is mapped to human chromosome Xq28. It contains 29 exons that encode a protein of 1257 amino acids containing a 19 amino acid signal peptide and a functional L1 protein of 1238 amino acids. It is mainly expressed in the nervous system.

Biochem/physiol Actions

L1 cell adhesion molecule (L1CAM) is critical for central nervous system (CNS) development in humans. This protein is responsible for many activities among them: neurite outgrowth, adhesion, fasciculation and myelination. These activities are mediated by the interaction of L1CAM with various members of the CAM protein family, extracellular matrix molecules and signaling receptors, through interactions that involve the extracellular domain of L1CAM. Mutations in the L1CAM gene may be linked to several brain disorders such as type 1 X-linked spastic paraplegia (SPG1), MASA syndrome and ACC (agenesis of corpus callosum).

The gene L1CAM (L1 cell adhesion molecule) encodes a glycoprotein that functions in axon growth during development and axon bundling. It interacts with Schwann cells and axons, and mediates neuronal cell migration, and neuronal cell survival. Overexpression of this protein is associated with tumor progression. It has been found to mediate therapeutic resistance in ovarian and pancreatic cancer cells.
