CC -!- FUNCTION: Postsynaptic MAGUK scaffold protein that links CADM1 cell
CC adhesion molecules to core components of the postsynaptic density
CC (PubMed:27756895). In CA1 pyramidal neurons, required for synaptic
CC KCNN2-containing channel function and long-term potentiation expression
CC (By similarity). Seems to negatively regulate SRC function in
CC epithelial cells (By similarity). {ECO:0000250|UniProtKB:Q14168,
CC ECO:0000250|UniProtKB:Q9WV34, ECO:0000269|PubMed:27756895}.
CC -!- SUBUNIT: Can homomultimerise (PubMed:27756895). Interacts with CACNG2
CC (PubMed:27756895). Interacts (via the SH3-Guanylate kinase-like sub-
CC module) with DLG4/PSD95 and DLGAP1/GKAP (PubMed:27756895). Interacts
CC (via the PDZ domain) with CADM1 (via C-terminus) (PubMed:27756895).
CC Interacts with KCNN2/SK2 (via N-terminal domain) (By similarity).
CC Interacts with SRC (By similarity). {ECO:0000250|UniProtKB:Q14168,
CC ECO:0000250|UniProtKB:Q9WV34, ECO:0000269|PubMed:27756895}.
CC -!- SUBCELLULAR LOCATION: Cell projection, dendrite
CC {ECO:0000250|UniProtKB:Q9WV34}. Postsynaptic density
CC {ECO:0000269|PubMed:27756895}. Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:Q14168}. Membrane
CC {ECO:0000250|UniProtKB:Q14168}. Note=Prominently expressed in the
CC postsynaptic densities of dendritic spines, is also detected in
CC dendritic shafts. {ECO:0000250|UniProtKB:Q9WV34}.
CC -!- TISSUE SPECIFICITY: Expressed in hippocampal neurons.
CC {ECO:0000269|PubMed:27756895}.
CC -!- PTM: Phosphorylated by SRC. {ECO:0000250|UniProtKB:Q14168}.
CC -!- SIMILARITY: Belongs to the MAGUK family. {ECO:0000305}.
