GIPC1 belongs to a family of evolutionarily conserved adaptor proteins responsible for the trafficking of numerous transmembrane proteins via endocytosis. Members of GIPC (GAIP interacting protein, C-terminus) have three main domains responsible for protein interactions; a PDZ domain which is flanked by GH1 and GH2 domains. GH1 domain is responsible for the dimerization of the protein, while GH2 is important for the interaction of GIPC1 with MYO6, a retrograde motor protein involved in protein trafficking. The PDZ domain of GIPC1 is responsible for the protein to interact with numerous proteins; namely β1-adrenoceptor, D2 dopamine receptor, GLUT1, TrkA receptor just to name a few. The zebrafish ortholog also interacts with Neuropilin-21,2.
GIPC1 expression is upregulated in breast, ovarian and pancreas cancers2.
