This section provides a summary of the gene/protein's function, expression, and relevance to neurodegenerative diseases.
NTSR1 encodes the high-affinity neurotensin receptor 1 (NTSR1), a G protein-coupled receptor (GPCR) that binds neurotensin with nanomolar affinity. NTSR1 is a Class A GPCR that couples primarily to Gq proteins, activating phospholipase C, leading to PKC activation and calcium mobilization. It also activates MAPK/ERK signaling pathways. In the brain, NTSR1 is expressed in regions rich in dopaminergic neurons and modulates dopamine signaling. It is also expressed in various peripheral tissues and cancers.
High expression in brain, particularly in substantia nigra, ventral tegmental area, hypothalamus, and amygdala. Also expressed in peripheral tissues including heart, lung, liver, and various tumors. In the CNS, NTSR1 is primarily located on neurons.
