Mycobacterial phage TM4 requires a eukaryotic-like Ser/Thr protein kinase to silence and escape anti-phage immunity.

In eukaryotic cells, serine/threonine protein kinases (StpKs) play important roles in limiting viral infections. StpKs are commonly activated upon infections, inhibiting the expression of genes central for viral replication. Here, we report that a eukaryotic-like StpK7 encoded by MSMEG_1200 in M.
