Agonist-induced Threonine306/Threonine310 phosphorylation of the FFA2 Receptor
pT306/pT310-FFA2 (phospho-FFA2 Antibody)
Threonine306/Threonine310 (T306/T310) is major phosphorylation site of the FFA 2 Receptor (FFA2). The pT306/pT310-FFA2 antibody detects phosphorylation in response to agonists. T306/T310 phosphorylation is likely to be involved in...

Constitutive Serine296/Serine297 phosphorylation of the FFA Receptor 2
pS296/pS297-FFA2 (phospho-FFA2 Antibody)
Serine296/Serine297 (S296/S297) is major phosphorylation site of the FFA Receptor 2 (FFA2). The pS296/pS297-FFA2 antibody detects constitutive phosphorylation of FFA2.

Validation of the FFA2 in transfected HEK293 cells
FFA2 (non-phospho-FFA2 Antibody)
The non-phospho-FFA2 receptor antibody is directed against the distal part of the carboxyl-terminal tail of human FFA2. It can be used to detect total FFA2 receptors in Western blots independent of phosphorylation. The non-phospho-FFA2...

FFA2 is predominantly expressed in adipose, inflammatory cells and the GI-tract. Elevation of FFA2 expression was observed in adipose of mice fed a high-fat diet compared that of mice on a low-fat diet suggesting a role in adipogenesis. FFA2 may be involved in the regulation of GI gastrointestinal motility and secretion since the receptor co-localizes with PYY in mucosal epithelium and mast cells. Expression of FFA2 has also been described in mouse pancreas with increased expression in islets from db/db and ob/ob mice. FFA2 is mainly coupled to Gαq. Acetate and propionate are the most potent ligands for the receptor with pentanoate less active. FFA2 receptor desensitization, β-arrestin recruitment and internalization are regulated by phosphorylation of carboxyl-terminal serine296/serine297 (pS296/pS297-FFA2) and threonine306/threonine310 (pT306/pT310-FFA2). This nomenclature refers to the human FFA2 receptor. For more information on FFA2 pharmacology please refer to the IUPHAR database. For further reading refer to:
