Anti-Tachykinin Receptor 1 (TACR1, TAC1R, Neurokinin 1 Receptor, NK1 Receptor, NK-1 Receptor, NK-1R,

NK1R (Neurokinin-1 receptor), gene name TACR1 (tachykinin receptor-1), is an 80kD 7-transmembrane glycoprotein receptor for the proinflammatory tachykinin neuropeptide, substance P. NK1R is constitutively or inducibly expressed on a wide variety of cells, including monocytes, macrophages, microglia, lymphocytes, neutrophils, mast cells, and neurons. The 407aa human NK1R contains 89 extracellular aa over multiple segments which collectively share 92aa identity with corresponding regions of mouse and rat NK1R. A 50kD short isoform that ends at aa311 lacks almost all of the C-terminal cytoplasmic signaling region. It is the only form expressed in human monocytes and undifferentiated THP-1 cells, and its function appears to differ from the long isoform. Applications: Suitable for use in Western Blot.
