Synthesis pass · prose summary of the discoveries below

ADIPOR1 is a seven-transmembrane adiponectin receptor that functions as a central metabolic sensor coupling adiponectin signaling to AMPK activation, mitochondrial biogenesis, lipid homeostasis, and anti-inflammatory responses across diverse tissues including skeletal muscle, liver, brain, retina, and immune cells. Upon adiponectin binding, ADIPOR1 induces extracellular Ca²⁺ influx to activate CaMKKβ→AMPK→SIRT1→PGC-1α signaling, promoting mitochondrial content and exercise capacity, and signals through APPL1→LKB1→AMPK to suppress hepatic gluconeogenesis and SREBP1c-driven lipogenesis (PMID:20357764, PMID:19254698, PMID:17268472). ADIPOR1 also possesses intrinsic ceramidase activity essential for maintaining membrane phospholipid unsaturation and DHA levels in photoreceptor outer segments; loss of this activity causes ceramide accumulation and retinal degeneration, and heterozygous or homozygous ADIPOR1 mutations cause retinitis pigmentosa in humans (PMID:35015730, PMID:30890562, PMID:27655171, PMID:26662040). In the brain, cell-type-specific ADIPOR1 deletion in serotonergic or dopaminergic neurons disrupts neurotransmitter homeostasis and produces depression- and anxiety-related phenotypes, while its surface availability is regulated post-translationally by ERp46 retention and translationally by miR-221/PTB-mediated repression (PMID:31980728, PMID:29988086, PMID:20074551, PMID:24130336).
