Chunk #15 — RESULTS — Differential expression of cell adhesion molecules and carbohydrate modifying enzymes suggests large capacity for cell surface and extracellular matrix labels
Each of the major synaptic adhesion families (e.g. neurexin, neuroligin, protein tyrosine phosphatases, leucine rich repeat proteins, Slitrks) is differentially expressed among PCPs (Figure 3D–F, Figure S3E). Cell specific expression of LRRs might contribute to post- and trans-synaptic specializations that customize the property of synapse types defined by pre- and post-synaptic neuron identities. Together, cell and synaptic adhesion families likely constitute a comprehensive mosaic of multi-faceted cell surface code throughout the neuronal membrane.
