General annotation (Comments)
| Function | 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 inhibition of apoptosis. Phosphorylates proteins 24 and 27, two critical regulators of capsid budding from nucleus to endoplasmic reticulum, thereby facilitating virion egress. Modulates and redistributes host components of the nuclear envelope, including LMNA, emerin/EMD and the nuclear matrix protein MATR3. Phosphorylates envelope glycoprotein B (gB), probably to direct it to the cell surface. Promotes virus intracellular spread by restructuring host cell cytoskeleton. Blocks host apoptosis to extend cell survival and allow efficient viral replication. Promotes viral gene expression by phosphorylating host HDAC2 to reduce viral genome silencing By similarity. Downregulates class I major histocompatibility complex (MHC-I) surface expression. Additionally, phosphorylates IE62 and targets it to the cytoplasm. The nuclear exclusion of IE62 enables the packaging of abundant levels of IE62 into virions. Ref.5 Ref.6 Ref.7 Ref.8 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subcellular location | Host cytoplasm By similarity. Host nucleus By similarity. |
| Post-translational modification | Phosphorylated by ORF47; this phosphorylation regulates subsequent phosphorylation of proteins 24 and 27 by ORF66. Autophosphorylated By similarity. Ref.4 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 protein kinase domain. |
