Scientific background

Mas-related G-protein coupled receptor member D (MRGPRD) is expressed in the dorsal root ganglia, specifically in non-peptidergic, small-diameter, IB4+ C-fiber neurons that innervate the outer layers of the mammalian skin. They transmit polymodal nociceptive information from the skin epidermis to the substantia gelatinosa of the spinal cord.

MRGPRD receptor expressing neurons are essential for the full expression of mechanical nociception. Thus, MRGPRD represents an attractive therapeutic target for the development of agents for treating pain^1,2.

The Mrg family in mice is comprised of six single-copy genes: MrgD, MrgE, MrgF/RTA, MrgG, MrgH/GPR90, and MAS1. In addition, there are three large subfamilies: MrgA, MrgB,and MrgC³.

MRGPRD receptor is activated by β-alanine and is able to inhibit KCNQ/M-type potassium channels and to increase excitability of sensory neurons^4,5. MRGPRD has the ability to form heterodimers and is encoded by the TGR7 gene. This receptor is co-expressed with two nociceptors, including purinergic receptor (P2X3) and a vanilloid receptor (VR1)⁵.

Scientific Background

Specific Control Product

MRGPRD/GPCR TGR7 Blocking Peptide (#BLP-MR061) is the original antigen used for immunization during Anti-MRGPRD (GPCR TGR7) Antibody (#AMR-061) generation. The blocking peptide binds and ‘blocks’ Anti-MRGPRD/GPCR TGR7 primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.
