Modifies the subcellular distribution of heterogeneous nuclear ribonucleoprotein K (HNRNPK) and may contribute to modulate HNRNPK functions related to processing and export of mRNAs during ASFV infection (PubMed:18775702). Necessary for virus internalization (PubMed:9568043). Oligomer. Interacts with host HNRNPK. Expressed in the early phase of the viral replicative cycle. Phosphorylated on serine residues in the 115 N-terminal amino acids. Belongs to the asfivirus phosphoprotein p30 family.
