Applications: Western blot, Immunoprecipitation, Immunofluorescence, FACS INFO: Deposited by Jesaitis, A.J. - Montana State University . INFO: The juxtamembrane epitope recognized by NFPRa is conserved in FPR1 and FPR2 (formerly FPRL1; 45 kDa) and is located on the cytoplasmic face of the receptor. Its recognition by NFPRa is insensitive to phosphorylation of either receptor.
