Adiponectin receptor 1 (AdipoR1) is a protein which in humans is encoded by the ADIPOR1 gene. [5] It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR1. [6]

Similar to G protein-coupled receptors (GPCRs), AdipoR1 also possesses 7 transmembrane domains. However, AdipoR1 is orientated oppositely to GPCRs in the membrane (i.e., cytoplasmic N-terminus, extracellular C-terminus) and does not associate with G proteins. [5]
The adiponectin receptors, AdipoR1 and AdipoR2, serve as receptors for globular and full-length adiponectin and mediate increased AMPK and PPAR-α ligand activities, as well as fatty acid oxidation and glucose uptake by adiponectin. [5] [7] In 2016, the University of Tokyo announced that it would launch an investigation into claims of fabrication of AdipoR1 and AdipoR2 identification data, as accused by an anonymous person/group called Ordinary_researchers.

Adiponectin is a protein hormone and adipokine, which is involved in regulating glucose levels and fatty acid breakdown. In humans, it is encoded by the ADIPOQ gene and is produced primarily in adipose tissue, but also in muscle and even in the brain.
Resistin also known as adipose tissue-specific secretory factor (ADSF) or C/EBP-epsilon-regulated myeloid-specific secreted cysteine-rich protein (XCP1) is a cysteine-rich peptide hormone derived from adipose tissue that in humans is encoded by the RETN gene.
Kir6.2 is a major subunit of the ATP-sensitive K+ channel, a lipid-gated inward-rectifier potassium ion channel. The gene encoding the channel is called KCNJ11 and mutations in this gene are associated with congenital hyperinsulinism.
The prolactin-releasing peptide receptor (PrRPR) also known as G-protein coupled receptor 10 (GPR10) is a protein that in humans is encoded by the PRLHR gene.
Somatostatin receptor type 5 is a protein that in humans is encoded by the SSTR5 gene.
Arctigenin is a lignan found in certain plants of the Asteraceae, including the greater burdock and Saussurea heteromalla. It has shown antiviral and anticancer effects in vitro. It is the aglycone of arctiin.
Somatostatin receptor type 1 is a protein that in humans is encoded by the SSTR1 gene.
The beta-3 adrenergic receptor (β3-adrenoceptor), also known as ADRB3, is a beta-adrenergic receptor, and also denotes the human gene encoding it.
ATP-binding cassette transporter sub-family C member 8 is a protein that in humans is encoded by the ABCC8 gene. ABCC8 orthologs have been identified in all mammals for which complete genome data are available.
Ectonucleotide pyrophosphatase/phosphodiesterase family member 1 is an enzyme that in humans is encoded by the ENPP1 gene.
Insulin gene enhancer protein ISL-1 is a protein that in humans is encoded by the ISL1 gene.
Intelectin-1, also known as omentin or intestinal lactoferrin receptor, is an intelectin encoded in humans by the ITLN1 gene. Intelectin-1 functions both as a receptor for bacterial arabinogalactans and for lactoferrin.
Glucose-6-phosphatase 2 is an enzyme that in humans is encoded by the G6PC2 gene.
Membrane progesterone receptor beta (mPRβ), or progestin and adipoQ receptor 8 (PAQR8), is a protein that in humans is encoded by the PAQR8 gene.
Adiponectin receptor 2 (AdipoR2) is a protein which in humans is encoded by the ADIPOR2 gene. It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR2.
Krüppel-like factor 15 is a protein that in humans is encoded by the KLF15 gene in the Krüppel-like factor family. Its former designation KKLF stands for kidney-enriched Krüppel-like factor.
Membrane progesterone receptors (mPRs) are a group of cell surface receptors and membrane steroid receptors belonging to the progestin and adipoQ receptor (PAQR) family which bind the endogenous progestogen and neurosteroid progesterone, as well as the neurosteroid allopregnanolone. Unlike the progesterone receptor (PR), a nuclear receptor which mediates its effects via genomic mechanisms, mPRs are cell surface receptors which rapidly alter cell signaling via modulation of intracellular signaling cascades. The mPRs mediate important physiological functions in male and female reproductive tracts, liver, neuroendocrine tissues, and the immune system as well as in breast and ovarian cancer.
The adiponectin receptors (AdipoRs) include the following two receptors, which are bound and activated by adiponectin:
AdipoRon is a selective, orally active, synthetic small-molecule agonist of the adiponectin receptor 1 (AdipoR1) and adiponectin receptor 2 (AdipoR2). It activates AMPK and PPARα signaling and ameliorates insulin resistance, dyslipidemia, and glucose intolerance in db/db mice. Moreover, AdipoRon has been found to extend the lifespans of db/db mice fed a high-fat diet, as well as improve exercise endurance. The compound was discovered by Japanese researchers in 2013 via screening of a compound library, and is the first orally active, small-molecule agonist of the adiponectin receptors to be identified.
PPARG coactivator 1 alpha is a protein that in humans is encoded by the PPARGC1A gene.
