CC   -!- FUNCTION: Plays an essential role in virion assembly and morphogenesis.
CC       Also plays a role in the inhibition of host immune response by
CC       dysregulating mTOR. Sequesters host RICTOR and RPTOR, thereby
CC       disrupting mTORC1 and mTORC2 crosstalk. In turn, blocks the host
CC       antiviral response in part through mTOR-dependent degradation of cGAS,
CC       the primary poxvirus sensor. {ECO:0000250|UniProtKB:P07396}.
CC   -!- SUBUNIT: Self-associates to form high molecular-weight forms. Interacts
CC       with protein A30. Interacts with host RICTOR and RPTOR; these
CC       interactions disrupt the mTORC1 and mTORC2 crosstalk.
CC       {ECO:0000250|UniProtKB:P07396}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:P07396}. Note=Major
CC       component of the virion comprising about 10% of the virion mass.
CC       {ECO:0000250|UniProtKB:P07396}.
CC   -!- PTM: Phosphorylated on two serines. While these phosphorylations do not
CC       play a role in virion assembly; they are essential for the interaction
CC       with host RICTOR and RPTOR. {ECO:0000250|UniProtKB:P07396}.
CC   -!- SIMILARITY: Belongs to the poxviridae F17 protein family.
CC       {ECO:0000305}.
