Correlation of lysosomal clusters with transcription factors. Lysosomal gene clusters identified in Figure 2 were used as reference sets for correlation analyses with known transcription factors as in Figure 1. Left panels, Mouse430_2 datasets. Right panels, human HG_U133_Plus2 datasets. Each plot shows the results for the 10 highest-ranking transcription factors; only DNA-binding proteins (GO:0003677) are shown. Complete results are given in Additional file 7.
