UniProt functional annotation for Q14168

UniProt code: Q14168.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Postsynaptic MAGUK scaffold protein that links CADM1 cell adhesion molecules to core components of the postsynaptic density (By similarity). In CA1 pyramidal neurons, required for synaptic KCNN2- containing channel function and long-term potentiation expression (By similarity). Seems to negatively regulate SRC function in epithelial cells (PubMed:19665017). {ECO:0000250|UniProtKB:D3ZAA9, ECO:0000250|UniProtKB:Q9WV34, ECO:0000269|PubMed:19665017}.
 
Subunit: Can homomultimerise. Interacts with CACNG2. Interacts (via the SH3-Guanylate kinase-like sub-module) with DLG4/PSD95 and DLGAP1/GKAP. Interacts (via the PDZ domain) with CADM1 (via C-terminus) (By similarity). Interacts with KCNN2/SK2 (via N-terminal domain) (By similarity). Interacts with SRC (PubMed:19665017). {ECO:0000250|UniProtKB:D3ZAA9, ECO:0000250|UniProtKB:Q9WV34, ECO:0000269|PubMed:19665017}.
Subcellular location: Cytoplasm, cytoskeleton {ECO:0000269|PubMed:19665017}. Membrane {ECO:0000269|PubMed:19665017}. Cell projection, dendrite {ECO:0000250|UniProtKB:Q9WV34}. Cell junction, synapse, postsynaptic density {ECO:0000250|UniProtKB:Q9WV34}. Note=Prominently expressed in the postsynaptic densities of dendritic spines, is also detected in dendritic shafts. {ECO:0000250|UniProtKB:Q9WV34}.
Ptm: Phosphorylated by SRC. {ECO:0000269|PubMed:19665017}.
Similarity: Belongs to the MAGUK family. {ECO:0000305}.
