Detection of Human NK1R by Western Blot. Western blot shows lysates of THP‑1 human acute monocytic leukemia cell line. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human NK1R Monoclonal Antibody (Catalog # MAB6687) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for NK1R at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 5.

NK1R (Neurokinin-1 receptor), gene name TACR1 (tachykinin receptor-1), is an ~80 kDa 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 407 amino acid (aa) human NK1R contains 89 extracellular aa over multiple segments which collectively share 92% aa identity with corresponding regions of mouse and rat NK1R. A ~50 kDa short isoform that ends at aa 311 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.
R&D Systems personnel manually curate a database that contains references using R&D Systems products.
The data collected includes not only links to publications in PubMed,
but also provides information about sample types, species, and experimental conditions.
