NRCAM (Neuronal Cell Adhesion Molecule), a member of the L1 family of immunoglobulin (Ig) cell adhesion molecules (CAMs), plays critical roles in neural development, synaptic plasticity, and cellular signaling. It is a transmembrane glycoprotein composed of six IgG-like domains, five fibronectin type III (FNIII) repeats, a single-pass transmembrane region, and a cytoplasmic tail. NRCAM facilitates homophilic and heterophilic interactions with other CAMs, extracellular matrix components, and receptors to regulate axon guidance, neurite outgrowth, and synapse formation during nervous system development.
Recombinant NRCAM protein refers to a lab-engineered version produced using expression systems like mammalian cells, insect cells, or bacteria. This purified protein retains functional domains necessary for binding and signaling studies while eliminating variability inherent in native tissue-derived samples. Researchers widely use it to investigate mechanisms of neuronal connectivity, cell migration, and tumor progression, as NRCAM is implicated in cancers (e.g., glioblastoma, melanoma) and neurological disorders (e.g., autism spectrum disorders, schizophrenia). Its overexpression or mutations may disrupt cell adhesion, promote metastasis, or impair synaptic function.
The production of recombinant NRCAM often involves tagging (e.g., Fc, His-tag) to enable detection, purification, or immobilization in assays. Studies leveraging this protein have clarified its role in modulating voltage-gated sodium channels and β-amyloid pathology in Alzheimer’s models. As a tool, it aids in drug discovery, antibody development, and structural analysis, offering insights into CAM-mediated therapeutic strategies. Despite progress, functional crosstalk with other L1-family members (e.g., L1CAM, CHL1) and context-dependent signaling mechanisms remain active research areas.
