Dual specificity phosphatase 4 (DUSP4) is a gene that encodes a protein that belongs to the dual specificity protein phosphatase subfamily. The protein functions in the negative regulation of members of the mitogen-activated protein kinase family. The inactivation of these kinases is achieved by dephosphorylation. Fusions, missense mutations, silent mutations, nonstop extensions, and frameshift insertions are observed in cancers such as intestinal cancer, skin cancer, and stomach cancer.

DUSP4 is altered in 1.79% of all cancers with colon adenocarcinoma, lung adenocarcinoma, prostate adenocarcinoma, breast invasive ductal carcinoma, and high grade ovarian serous adenocarcinoma having the greatest prevalence of alterations [3].
