CC   -!- FUNCTION: Inhibits IFN-gamma synthesis. Down-regulates the expression
CC       of the host TAP1 gene (transporter associated with antigen processing),
CC       thereby affecting the transport of peptides into the endoplasmic
CC       reticulum and subsequent peptide loading by MHC class I molecules. In
CC       consequence, infected cells are masked for immune recognition by
CC       cytotoxic T-lymphocytes (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the IL-10 family. {ECO:0000305}.
CC   -!- CAUTION: Be careful of the possible confusion between BCRF1 with BcRF1.
CC       {ECO:0000305}.
