General description

Substance-P receptor (UniProt P14600; also known as Neurokinin-1 receptor, NK-1 receptor, NK-1R, SPR, Tachykinin receptor 1) is encoded by the Tacr1 (also known as Nk1r, Tac1r) gene (Gene ID 24807) in rat species. NK-1, NK-2 and NK-3 are receptors that mediate the biological activities of tachykinins, including substance P (SP), neurokinin A (NKA), neurokinin B (NKB), ranakinin, kassinin, neuropeptide gamma, and eledoisin, widely distributed in the central and peripheral nervous systems. SP shows the highest affinity toward NK-1R (substance-P receptor) and exerts its biological activities via NK-1R, including addition, depression, chronic inflammation, and cancer progression. The involvement of NK-1R in acute pancreatitis through mediating neurogenic inflammation has also been reported. Upon stimulation by SP, the NK-1R interacts with multiple G proteins, including Gαs, Gαq/11, Gαi/o, Gα12, and Gα13, generating second messengers and activating downstream effector molecules. After binding NK-1R, SP induces a clathrin-dependent internalization of the receptor-ligand complex, SP is then degraded and the receptor is recycled to the cell surface. NK-1R is a 7-transmembrane (32-54, 65-86, 107-128, 149-169, 195-219, 249-270, 284-308) GPCR, having its N-terminal end (a.a. 1-31) at the extracelluar side and C-terminal end (a.a. 309-407) at the cytoplasmic side. There exist a second alternatively spliced human NK-1R isoform that lacks the C-terminal cytoplasmic domain (a.a. 312-407 missing). The full-length form enhances the growth of cancer cells and stimulates the production of cytokines, which up-regulate the truncated form. The truncated form mediates malignancy and is more abundant in colonic epithelial cells from patients with colitis-associated cancer. In cancer cells, the NK-1 receptor is mainly localized on the plasma membrane and in cytoplasm, and occasionally also in the nucleus.

Specificity

This guinea pig polyclonal antiserum targets substance P receptor C-terminal end sequence. Target region is absent in human spliced isoform 2.

Immunogen

Epitope: C-Terminus
KLH-conjugated linear peptide corresponding to the C-terminal end sequence of rat substance P receptor.

Application

Research Category
Neuroscience
Research Sub Category
Synapse & Synaptic Biology
This Guinea pig polyclonal Anti-Substance P Receptor Antibody, Cat. No. AB15810 detects levels of Substance P receptor, and has been published and validated for use in Immunohistochemistry, and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected substance P receptor in 10 µg of human brain tissue lysate.

Immunohistochemistry Analysis: A 1:500 dilution from a representative lot detected substance P receptor in rat brain tissue sections.

Quality

Evaluated by Western Blotting in rat brain tissue lysate.

Western Blotting Analysis: A 1:5000 dilution from a representative lot detected substance-P receptor in 10 µg of rat brain tissue lysate.

Target description

~58/54 kDa observed. Target band size appears larger than the calculated molecular weights of 46.25/46.32/46.37 kDa (human/mouse/rat) due to glycosylation. Uncharacterized bands may be observed in some lysate(s).

Physical form

Format: Unpurified
Guinea Pig polyclonal antibody serum with 0.05% sodium azide
Unpurified.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.

Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
