SALM1, SALM2, and SALM3 form homo- and heteromeric complexes in a cis manner. These SALMs 1-3 coimmunoprecipitate with each other in extracts from brain. Whether the homo and heteromeric complexes formed between SALMs 1-3 contribute to synapse formation or neurite outgrowth remains to be determined (Seabold et al. 2008).
