Comparison of GIN2-containing genomic regions in vertebrates. Synteny analysis was performed using Ensembl (http://www.ensembl.org/index.html), Genomicus (http://www.dyogen.ens.fr/genomicus-66.01/cgi-bin/search.pl), and BLAST analysis (http://blast.ncbi.nlm.nih.gov/Blast.cgi). Genes represented by white boxes are not found in this region in fish. Black boxes from stickleback represent different genes from ABCB9, VPS37B, and PPP3C in other fish. Their Ensembl accession numbers are from right to left: ENSGACG00000013652, ENSGACG00000013659, and ENSGACG13660.
