CC -!- FUNCTION: Mediates homophilic cell-cell adhesion in a Ca(2+)- CC independent manner (PubMed:12050160, PubMed:22438059). Also mediates CC heterophilic cell-cell adhesion with CADM3 and NECTIN3 in a Ca(2+)- CC independent manner (By similarity). Interaction with CRTAM promotes CC natural killer (NK) cell cytotoxicity and interferon-gamma (IFN-gamma) CC secretion by CD8+ cells in vitro as well as NK cell-mediated rejection CC of tumors expressing CADM1 in vivo (PubMed:15811952). In mast cells, CC may mediate attachment to and promote communication with nerves CC (PubMed:15905536). CADM1, together with MITF, is essential for CC development and survival of mast cells in vivo (PubMed:22438059). By CC interacting with CRTAM and thus promoting the adhesion between CD8+ T- CC cells and CD8+ dendritic cells, regulates the retention of activated CC CD8+ T-cell within the draining lymph node (By similarity). Required CC for the intestinal retention of intraepithelial CD4+ CD8+ T-cells and, CC to a lesser extent, intraepithelial and lamina propria CD8+ T-cells and CC CD4+ T-cells (By similarity). Interaction with CRTAM promotes the CC adhesion to gut-associated CD103+ dendritic cells, which may facilitate CC the expression of gut-homing and adhesion molecules on T-cells and the CC conversion of CD4+ T-cells into CD4+ CD8+ T-cells (By similarity). Acts CC as a synaptic cell adhesion molecule and plays a role in the formation CC of dendritic spines and in synapse assembly (By similarity). May be CC involved in neuronal migration, axon growth, pathfinding, and CC fasciculation on the axons of differentiating neurons (By similarity). CC May play diverse roles in the spermatogenesis including in the adhesion CC of spermatocytes and spermatids to Sertoli cells and for their normal CC differentiation into mature spermatozoa (By similarity). Acts as a CC tumor suppressor in non-small-cell lung cancer (NSCLC) cells CC (PubMed:11279526, PubMed:12234973). May contribute to the less invasive CC phenotypes of lepidic growth tumor cells (PubMed:12920246).

CC -!- FUNCTION: [Isoform 5]: (Microbial infection) Induces cell fusion in CC neuron infected by a neuropathogenic strain of measles. Interacts with CC measles hemagglutinin to trigger hyperfusogenic F-mediated membrane CC fusion and presumably transsynaptic cell-to-cell transmission of the CC virus. {ECO:0000269|PubMed:37166307}. CC -!- SUBUNIT: Homodimer (via Ig-like V-type domain) (PubMed:12050160, CC PubMed:23871486). Interacts with FARP1 (By similarity). Interacts (via CC Ig-like V-type domain) with CRTAM (via Ig-like V-type domain); the CC interaction competes with CRTAM homodimerization and CADM1 CC homodimerization (PubMed:15781451, PubMed:15811952, PubMed:23871486). CC Interacts (via C-terminus) with EPB41L3/DAL1 (PubMed:12234973, CC PubMed:21131357). The interaction with EPB41L3/DAL1 may act to anchor CC CADM1 to the actin cytoskeleton (PubMed:12234973). Interacts (via C- CC terminus) with MPP2 (via PDZ domain) (By similarity). Interacts (via C- CC terminus) with MPP3 (via PDZ domain); this interaction connects CADM1 CC with DLG1 (PubMed:13679854, PubMed:24503895). Interacts (via C- CC terminus) with PALS2 (via PDZ domain) (By similarity).
