Summary: Predicted to enable signaling receptor activity. Involved in positive regulation of fatty acid oxidation; response to cold; and tail spike morphogenesis. Located in plasma membrane. Is expressed in gonadal sheath cell; head muscle; nervous system; and seam cell. Human ortholog(s) of this gene implicated in breast cancer; macular degeneration; metabolic dysfunction-associated steatotic liver disease; prostate adenocarcinoma; and type 2 diabetes mellitus. Orthologous to human ADIPOR1 (adiponectin receptor 1) and ADIPOR2 (adiponectin receptor 2). [provided by Alliance of Genome Resources, Dec 2024]

AdipoR2 recruits protein interactors to promote fatty acid elongation and membrane fluidity.
Title: AdipoR2 recruits protein interactors to promote fatty acid elongation and membrane fluidity.
The C. elegans PAQR-2 and IGLR-2 membrane homeostasis proteins are uniquely essential for tolerating dietary saturated fats.
Title: The C. elegans PAQR-2 and IGLR-2 membrane homeostasis proteins are uniquely essential for tolerating dietary saturated fats.
We conclude that acs-13 mutations in C. elegans and ACSL1 knockdown in human cells prevent lipotoxicity by promoting increased levels of polyunsaturated fatty acid-containing phospholipids
Title: Evolutionarily conserved long-chain Acyl-CoA synthetases regulate membrane composition and fluidity.
The Caenorhabditis elegans adiponectin receptor AdipoR2 homolog PAQR-2 signaling detects temperature drop and augments the biosynthesis of two omega-6 polyunsaturated fatty acids, gamma-linolenic acid and arachidonic acid. These two polyunsaturated fatty acids in turn initiate autophagy in the epidermis, delaying an age-dependent decline in collagen contents, and extending the lifespan.
Title: Adiponectin receptor PAQR-2 signaling senses low temperature to promote C. elegans longevity by regulating autophagy.
We conclude that the PAQR-2 and AdipoR2 proteins share an evolutionarily conserved function that maintains membrane fluidity in the presence of exogenous saturated fatty acids.
Title: The adiponectin receptor AdipoR2 and its Caenorhabditis elegans homolog PAQR-2 prevent membrane rigidification by exogenous saturated fatty acids.
PAQR-2 and IGLR-2 interact on plasma membranes and thus may act together as a fluidity sensor that controls membrane lipid composition.
Title: Caenorhabditis elegans PAQR-2 and IGLR-2 Protect against Glucose Toxicity by Modulating Membrane Lipid Composition.
This model is supported by the observations that the paqr-2 suppressors normalize the levels of saturated fatty acids, and that low concentrations of detergents that increase membrane fluidity can rescue the paqr-2 mutant.
Title: PAQR-2 regulates fatty acid desaturation during cold adaptation in C. elegans.
