MST4, also known as MASK, is a member of the germinal center kinase III subfamily, which belongs to the larger Sterile 20-related family of kinases, which are known to be involved in signaling through MAPK pathways.16 MST4 has been shown to regulate multiple cellular aspects, such as cell proliferation and polarity,17 and has also been shown to activate ERK as well as contribute to the transformation of Phoenix cells.16, 18, 19 Therefore, it is evident that MST4 has certain functions that may aid tumor growth. Here, STK26 is linked to neoplasm.
