CC -!- FUNCTION: May regulate immune response to the intracellular capsid in
CC acting as a T-cell tolerogen, by having an immunoregulatory effect
CC which prevents destruction of infected cells by cytotoxic T-cells.
CC {ECO:0000256|RuleBase:RU361253}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000256|RuleBase:RU361253}.
CC -!- PTM: Cleaved by host furin. {ECO:0000256|RuleBase:RU361253}.
CC -!- PTM: Phosphorylated. {ECO:0000256|RuleBase:RU361253}.
CC -!- SIMILARITY: Belongs to the orthohepadnavirus precore antigen family.
CC {ECO:0000256|RuleBase:RU361253}.
