Genomic arrangements of SCPP genes and secreted protein acidic and rich in cysteine (SPARC)-family genes in the genomes of spotted gar, bowfin and the teleosts zebrafish, Mexican tetra (cavefish) and channel catfish. The direction of triangles and pentagons indicates the transcriptional direction of each gene, encoding P/Q-rich SCPPs (red), acidic SCPPs (blue) and SPARC-family proteins (yellow). Orthologs are connected by dashed lines; unresolved orthologies are indicated with a ‘?’. Intervening non-SCPP genes are not shown. In the zebrafish genome, a cluster of sparcl1 and scpp1 is separated by ~10 Mb from the other genes encoding P/Q-rich SCPPs (arrow). Two cavefish SCPP gene clusters are located on unplaced scaffolds. See Supplementary Data 1 and Source Data for SCPP gene predictions, locations and gene IDs.
