Genes affected

GRIP2 (HGNC:23841): (glutamate receptor interacting protein 2) Predicted to enable protein C-terminus binding activity. Predicted to be involved in several processes, including neurotransmitter receptor transport, endosome to postsynaptic membrane; positive regulation of AMPA glutamate receptor clustering; and positive regulation of excitatory postsynaptic potential. Predicted to act upstream of or within Notch signaling pathway; artery smooth muscle contraction; and positive regulation of blood pressure. Predicted to be located in cytoplasm; dendritic shaft; and neuron spine. Predicted to be active in glutamatergic synapse and postsynaptic density.
