Predicted to enable heparan sulfate proteoglycan binding activity. Predicted to be involved in regulation of synapse assembly. Predicted to act upstream of or within AMPA glutamate receptor clustering; positive regulation of synapse assembly; and regulation of presynaptic membrane organization. Predicted to be located in postsynaptic membrane. Predicted to be part of AMPA glutamate receptor complex. Predicted to be active in several cellular components, including GABA-ergic synapse; photoreceptor ribbon synapse; and postsynaptic density membrane.

A study in humans characterized the platelet transcriptome in acute myocardial infarction patients, identifying the LRRTM4 as having increased expression in non-ST-segment elevation myocardial infarction (NSTEMI) platelets compared to ST-segment elevation myocardial infarction (STEMI) platelets [Eicher et al. DOI:10.3109/09537104.2015.1083543].
