A complex puzzle: Regulation of SLFN12 RNase activity by phosphorylation
{{output}}
PDE3A-SLFN12 complex formation activates the SLFN12 RNase, but the biochemical details of RNase activation remain mysterious. In this issue of Cell Chemical Biology, Yan and colleagues report that two phosphoserines on SLFN12 are dephosphorylated in response t... ...
