Description

CADM1 mediates homophilic and heterophilic cell–cell adhesion at synaptic junctions and epithelial tight junctions, and its loss of expression correlates with tumor progression in multiple cancer types. This mammalian-expressed construct spans residues 45–374, encompassing the three extracellular immunoglobulin-like domains essential for receptor engagement, and demonstrates quantified binding to CRTAM with an EC50 of 17.82–21.71 ng/mL in functional ELISA. The measured affinity supports use in cell adhesion and spreading assays, tumor metastasis models examining epithelial integrity, and immune cell trafficking studies where CADM1–CRTAM interactions regulate NK and T cell activation. Purity exceeding 95% by SDS-PAGE and endotoxin levels below 1.0 EU/μg align with standards expected in antibody development campaigns and cell-based functional assays requiring minimal contaminant interference.

Target Background

Function

Mediates homophilic cell-cell adhesion in a Ca(2+)-independent manner. Also mediates heterophilic cell-cell adhesion with CADM3 and NECTIN3 in a Ca(2+)-independent manner. Interaction with CRTAM promotes natural killer (NK) cell cytotoxicity and interferon-gamma (IFN-gamma) secretion by CD8+ cells in vitro as well as NK cell-mediated rejection of tumors expressing CADM1 in vivo. In mast cells, may mediate attachment to and promote communication with nerves. CADM1, together with MITF, is essential for development and survival of mast cells in vivo. By interacting with CRTAM and thus promoting the adhesion between CD8+ T-cells and CD8+ dendritic cells, regulates the retention of activated CD8+ T-cell within the draining lymph node. Required for the intestinal retention of intraepithelial CD4+ CD8+ T-cells and, to a lesser extent, intraepithelial and lamina propria CD8+ T-cells and CD4+ T-cells. Interaction with CRTAM promotes the adhesion to gut-associated CD103+ dendritic cells, which may facilitate the expression of gut-homing and adhesion molecules on T-cells and the conversion of CD4+ T-cells into CD4+ CD8+ T-cells. Acts as a synaptic cell adhesion molecule and plays a role in the formation of dendritic spines and in synapse assembly. May be involved in neuronal migration, axon growth, pathfinding, and fasciculation on the axons of differentiating neurons. May play diverse roles in the spermatogenesis including in the adhesion of spermatocytes and spermatids to Sertoli cells and for their normal differentiation into mature spermatozoa. Acts as a tumor suppressor in non-small-cell lung cancer (NSCLC) cells. May contribute to the less invasive phenotypes of lepidic growth tumor cells.
