    Protocol

    Specificity / Sensitivity

    HCAR1/GPR81 (F9I8Q) Rabbit Monoclonal Antibody recognizes endogenous levels of total HCAR1 protein. This product shows nonspecific staining in stomach crypts by immunohistochemistry.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human HCAR1 protein.

    Background

    The hydroxycarboxylic acid receptor 1 (HCAR1), formerly known as GPR81, is a G protein-coupled receptor (GPCR) for endogenous lactate, connecting energy metabolism with neural function (1). HCAR1 was initially described in adipocytes, where its activation inhibits of lipolysis via the Gi-dependent intracellular pathway activation (1,2). More recently, HCAR1 has been identified to modulate neuronal network activity through the activation of Gα and Gβγ subunits (3). Furthermore, HCAR1 was found to be a key modulator of pathways that promote tissue regeneration after hypoxia-ischemia and mitigate epileptic seizure activity in the brain (4,5). Besides its role in neurons, HCAR1 also directly influences astrocyte development and plays a role in metabolic regulation in glial cells during hypoglycemia (6).
