SAP102: Proteins and Enzymes

Synapse-Associated Protein 102 (SAP102) is one of a family of plasma membrane-associated proteins found in synaptic junctions. Like other members of the family, SAP102 has three ~90 amino acid repeats called PDZ domains followed by an SH3 domain and a yeast guanylate kinase homology (GuK) domain. It is hypothesized that PDZ-domain interactions play a role in receptor and channel clustering which contributes to neuronal plasticity. SAP102 is believed to participate in the clustering of ...
