Figure 2: Genomic organization of the CXC chemokine major cluster. The maps shown are based on the Ensembl Genome Browser and our analyses. The gene symbols for the two human CXCL7 pseudogenes (CXCL7-ps pseudogenes between CXCL6 and CXCL4L1 and between CXCL3 and CXCL15-ps) and one human CXCL1 pseudogene (CXCL1-ps) are PPBPP1 [18], PPBPP2, and CXCL1P [19], respectively. Genome sequences used for analysis with BLAST search are GRCm38 (mouse, Mus musculus), Rnor_5.0 (rat, Rattus norvegicus), spetri2 (squirrel, Ictidomys tridecemlineatus), cavPor3 (guinea pig, Cavia porcellus), oryCun2 (rabbit, Oryctolagus cuniculus), and GRCh37 (human, Homo sapiens).
