Description

CADM1 functions as a tumor suppressor and synaptic adhesion molecule whose interaction with CRTAM mediates critical immune cell recognition events relevant to cancer immunology. This recombinant mouse CADM1 (residues 48–388) encompasses the extracellular immunoglobulin-like domains required for trans-cellular binding, and functional ELISA confirms its activity with an EC50 of 52.61–92.92 ng/mL against mouse CRTAM, supporting use in integrin-ligand binding studies, tumor metastasis research, and antibody development campaigns targeting the CADM1–CRTAM axis. Mammalian cell expression preserves native glycosylation and disulfide-dependent folding essential for adhesion molecules, ensuring this protein is appropriate for cell adhesion and spreading assays as well as migration and invasion experiments where physiological conformation drives reproducible results. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for cell-based functional assays and immune cell trafficking studies without confounding inflammatory artifacts.

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+ T-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.
