CC -!- FUNCTION: Plays an essential role in the viral genome replication.
CC Participates, together with NSP2, in the formation of viral factories
CC (viroplasms) which are large inclusions in the host cytoplasm where
CC replication intermediates are assembled and viral RNA replication takes
CC place. Orchestrates the recruitment of viroplasmic proteins such as
CC capsid proteins to these factories. {ECO:0000255|HAMAP-Rule:MF_04092}.
CC -!- COFACTOR:
CC Note=Magnesium is required for ATPase activity.;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_04092};
CC -!- SUBUNIT: Homodimer. Interacts with VP1. Interacts with VP2. Interacts
CC with NSP2; this interaction leads to up-regulation of NSP5
CC hyperphosphorylation and formation of virus factories. Interacts with
CC NSP6. {ECO:0000255|HAMAP-Rule:MF_04092, ECO:0000269|PubMed:10675420}.
CC -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000255|HAMAP-Rule:MF_04092}.
CC Note=Found in spherical cytoplasmic structures, called virus factories,
CC that appear early after infection and are the site of viral replication
CC and packaging. {ECO:0000255|HAMAP-Rule:MF_04092}.
CC -!- PTM: O-glycosylated. {ECO:0000255|HAMAP-Rule:MF_04092}.
CC -!- PTM: Hyperphosphorylated on serine residues, when in dimeric form.
CC Phosphorylation by host CK1 is required for the hyperphosphorylation of
CC NSP5 dimer. {ECO:0000255|HAMAP-Rule:MF_04092,
CC ECO:0000269|PubMed:10675420}.
CC -!- SIMILARITY: Belongs to the rotavirus NSP5 family. {ECO:0000255|HAMAP-
CC Rule:MF_04092}.
