SHC3 Antibody – Rabbit

SHC3: an adapter protein containing an SH2 and a PID domain. Couples activated growth factor receptors to signaling pathway in neurons. Involved in the signal transduction pathways of neurotrophin-activated Trk receptors in cortical neurons and the regulation of NMDA receptor function in the hippocampus. May modulate hippocampal synaptic plasticity underlying learning and memory. Interacts with the Trk receptors in a phosphotyrosine-dependent manner. Once activated, binds to GRB2. Interacts with activated EGF receptors. Mainly expressed in brain. Hardly detectable in other tissues, except in pancreas. Highly expressed in the cerebral cortex, frontal and temporal lobes, occipital pole, hippocampus, caudate nucleus and amygdala. Expressed at low level in the cerebellum, medulla and spinal cord. A switch from Shc1 to Shc3 occurs during maturation of neuronal precursors to postmitotic neurons. Two alternatively spliced isoforms have been described.
