SKAP1 and leukemia: Interestingly, the colon cancer SW620 cells expressed higher levels of SKAP1 than Jurkat cells (Figure 1D,E), a human leukemic T‐cell line constitutively expressing SKAP1.[19] This was supported by the analytical results of 985 cancer cell lines from the Human Protein Atlas portal, which showed that the average expression level of SKAP1 in colorectal cancer cells was comparable to that in lymphoma and leukemia cells (Figure S1D, Supporting Information).
