Data Examples

Western Blot View Larger

Detection of Human FFAR3/GPR41 by Western Blot. Western blot shows lysates of A549 human lung carcinoma cell line and HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human FFAR3/GPR41 Monoclonal Antibody (Catalog # MAB10562) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for FFAR3/GPR41 at approximately 39 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: FFAR3/GPR41

GPR41 and GPR42 are two closely related genes that are part of a cluster of four adjacent G protein-coupled receptors(GPR40, 41, 42, and 43). There are only six nucleotide and amino acid differences between GPR41 and GPR42. GPR41 is a receptor for short chain fatty acids. The rank order of potency for agonists of this receptor ispropionate = pentanoate= butyrate > acetate > formate. The activity of this receptor is coupled to the formation of inositol 1,4,5-trisphosphate, intracellular Ca2+ mobilization, the activation of ERK 1/2 and inhibition of intracellular cAMP accumulation.

Long Name

Alternate Names
