Figure 1From: A formylpeptide receptor, FPRL1, acts as an efficient coreceptor for primary isolates of human immunodeficiency virusPhylogenetic tree of peptide receptors belonging to the GPCR family. The phylogenetic tree for 20 CKRs and 16 GPCRs related to CKRs was constructed by the ClustalW program [72] according to the methods described in the DDBJ website (National Institute of Genetics, Center for Information Biology and DNA Databank of Japan, http://www.ddbj.nig.ac.jp). FPRL1 is indicated by the arrow. GPCRs reported to function as HIV/SIV coreceptors are indicated by "*".Back to article page
