Chromosomal locations of the 331 genes coding for A. gambiae SP-related proteins. As indicated by the scale bar, positions of the genes are plotted in proportion on chromosomes, with “+” and “−” indicating positive and negative strands on the left and right, respectively. Note that CLIPE32, SP44, SP142, SPH12, SPH42, and SPH113 genes are not found in the genome assembly. Names of CLIPs (red), GP(H)s (green) and SP(H)s (blue) are linked to their locations by straight lines. Adjacent genes with high sequence similarities are grouped by lines in the same color and marked by a series of location IDs on red background for different chromosomal segments. Regions in between are labeled with IDs on blue background. In these IDs, the 1st letter (1–6) represent chromosome (Ch.) 2L, 2R, 3L, 3R, X and UNKN (unknown), respectively, and the 2nd letter in capital for gene clusters or in lowercase for other regions.
