The function of ENSG00000175161 (CADM2, cell adhesion molecule 2) is as follows. Adhesion molecule that engages in homo- and heterophilic interactions with the other nectin-like family members, leading to cell aggregation. Important for synapse organization, providing regulated trans-synaptic adhesion. Preferentially binds to oligodendrocytes. . [Isoform 5]: (Microbial infection) Induces cell fusion in neuron infected by a neuropathogenic strain of measles. Interacts with measles hemagglutinin to trigger hyperfusogenic F-mediated membrane fusion and presumably transsynaptic cell-to-cell transmission of the virus. .
