Full phosphorylation of SARS-CoV-2 nucleoprotein (N) depends on priming phosphorylations on at least two sites by SRPK1/2 protein kinases (Heaton et al, 2020; Carlson et al, 2020). Both kinases are monomers that need a magnesium cofactor to work, and are activated through phosphorylation by CK2 kinase (Daub et al, 2002).
