Figure 2. NMDAR sequence homology between human and polar bear.
Alignment of the extracellular N-terminal part of the human NR1 subunit of the NMDA receptor with the polar bear genome scaffold 203 demonstrating high sequence conservation across species. Identical sequences are marked by a dot. Different bases between human and polar bear are given, deletions are shown as a dash. The sequence highlighted in grey represents the epitope recognized by the majority of human NMDAR autoantibodies.
