Multifunctional serine/threonine kinase that plays a role in several processes including egress of virus particles from the nucleus, modulation of the actin cytoskeleton and regulation of viral and cellular gene expression. Regulates the nuclear localization of viral envelopment factor proteins 24 and 27, by phosphorylating the protein kinase ORF66, indicating a role in nuclear egress. Disrupts host nuclear lamins, including LMNA and LMNB1. Phosphorylates the viral Fc receptor composed of glycoproteins E (gE) and I (gI) (By similarity). Phosphorylation of glycoprotein E (gE) by UL13 alters its subcellular localization, from the host early endosome to the plasma membrane. Participates in the transcriptional regulation of cellular and viral mRNAs mainly by phosphorylating the viral transcriptional regulator IE63.

Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
