What pLDDT means and how to read it

Function

Cell surface protein involved in cell-cell-interactions via its interactions with neurexin family members. Plays a role in synapse function and synaptic signal transmission, and probably mediates its effects by recruiting and clustering other synaptic proteins. May promote the initial formation of synapses, but is not essential for this. May also play a role in glia-glia or glia-neuron interactions in the developing peripheral nervous system

Subunit structure

Homodimer, and heterodimer with NLGN1 and NLGN2 (By similarity). Interacts with neurexins NRXN1, NRXN2 and NRXN3 (By similarity). Interaction with neurexins is mediated by heparan sulfate glycan modification on neurexin (PubMed:30100184). Interacts (via its C-terminus) with DLG4/PSD-95 (via PDZ domain 3) (By similarity)

Subcellular location

Cell membrane, Synapse, Cell projection, dendrite
