Immunohistochemistry analysis of GPR26 was performed on human pancreatic islets tissue. To expose target proteins, antigen retrieval was performed by microwaving tissues for 20 minutes in 10mM sodium citrate buffer (pH 6.0). Tissue slides were probed with a GPR26 polyclonal antibody (Product # PA3-036) at a dilution of 1:3000, overnight at 4C in a humidified chamber. Tissues were washed, and detection was performed using an ABC kit composed of biotinylated goat anti-rabbit IgG, peroxidase-conjugated avidin, and 3-amino-9-ethylcarbazole (AEC) substrate in acetate buffer. Tissues were counterstained with hematoxylin and dehydrated to prep for mounting.

IHC (P) analysis shows positive staining of GPR26 in human pancreatic islets.
The G-protein-coupled receptor (GPCR) superfamily is comprised of an estimated 600-1,000 members and is the largest known class of molecular targets with proven therapeutic value. GPR26 is a brain-specific orphan GPCR with a significant level of constitutive activity. Its effect is mediated by G(s)-alpha protein that stimulate adenylate cyclase, resulting in an elevation of intracellular cAMP. In the CNS, the highest GPR26 expression is in the amygdala, hippocampus and thalamus. Weak expression is detected in testis. GPR26 is down-regulated in glioblastoma. Depletion of GPR26 has been shown to increase fat storage in C. elegans, whereas GPR26 deficiency in the hypothalamus is associated with high genetic susceptibility to the onset of obesity in mice. GPR26 deficiency also causes metabolic complications commonly associated with obesity, including glucose intolerance, hyperinsulinemia, and dyslipidemia.
