Background Information
GPR81 (G protein-coupled receptor 81) is one of a large family of GPRs with low affinity for hydroxy-carboxylic acid structure ligands (PMID: 24657625). Lactate functions as a signaling molecule by serving as an agonist for the GPR81, involving both autocrine and paracrine mechanisms (PMID: 31836453). Moreover, A higher molecular mass band (∼60 kDa) is present in the brain and adipose tissue. This band is also strong in the transfected HeLa cells but weak in native HeLa cells and is therefore probably a form of GPR81, possibly a glycosylated form of the receptor (PMID: 23696276).
