Annotation description:Fig. 6 MAGI2 interacts with NMDA
Literal
"The anti-S-SCAM antibody coimmunoprecipitated NMDAR1, whereas the preimmune serum did not.This result indicates that S-SCAM interacts with NMDA receptors in vivo."
Fig. 7 MAGI2 colocalyzed with PSD-95
Literal
"To examine the distribution of S-SCAM in neurons, we double-stained primary cultured rat hippocampal neurons on day 14 in the combination of anti-S-SCAM antibody with either anti-NMDAR1 or anti-PSD- 95/SAP90 antibody. The staining pattern of S-SCAM was similar to that of PSD-95/SAP90, which was detected in the cell body as well as at the dendrites (Fig. 7A). S-SCAM showed
distributions similar to those of NMDAR1 at dendrites (Fig.7B). Because SAPAP was distributed in a manner similar to that of PSD-95/SAP90 (Fig. 7C), S-SCAM was considered to be distributed in a manner similar to SAPAP.

Literal
"We also determined the distribution of S-SCAM in the subcellular fractions of rat brain by the immunoblotting with the anti-S-SCAM antibody. The signals detected with the antibody were distributed in both the cytosolic synaptosomal (S2) and
crude synaptosomal pellet (P2) fractions (Fig. 8).
