This includes OmniATAC-seq data of human melanoma cell lines (MM029, MM034, MM052, MM116, MM118, MM122, MM163, MM164, MM165; data for the other lines used in this study were published before [see “Publicly available data used in this work”]), two dog melanoma cell lines, two horse melanoma cell lines, one pig melanoma sample, one pig melanocyte cell line, and one mouse melanoma cell line; ATAC-seq data of four zebrafish cell lines; and OmniATAC-seq data of SOX10 and TFAP2A knockdown in the human melanoma cell line MM001. Here, TFAP2A is linked to melanoma.
