CC -!- FUNCTION: Multifunctional serine/threonine kinase that plays a role in
CC several processes including egress of virus particles from the nucleus,
CC modulation of the actin cytoskeleton and regulation of viral and
CC cellular gene expression. Regulates the nuclear localization of viral
CC envelopment factors UL34 and UL31 homologs, by phosphorylating the US3
CC kinase homolog, indicating a role in nuclear egress. Disrupts host
CC nuclear lamins, including LMNA and LMNB1. Phosphorylates the viral Fc
CC receptor composed of glycoproteins E (gE) and I (gI). Phosphorylation
CC of glycoprotein E (gE) by UL13 homolog alters its subcellular
CC localization, from the host early endosome to the plasma membrane.
CC Participates in the transcriptional regulation of cellular and viral
CC mRNAs mainly by phosphorylating the viral transcriptional regulator
CC ICP22 homolog (By similarity). {ECO:0000250}.
