The protein kinase PKMYT1 (Membrane Associated Tyrosine/Threonine 1), a member of the WEE kinase family, has been shown to play a negative role in the G2/M phase of the cell cycle and has been implicated in the development and progression of several cancers, including hepatic, glioblastoma, colorectal, and non-small cell lung cancers [29]. Here, WEE1 is linked to cancer.
