RT "Primary structures of two homologous subunits of PA28, a gamma-interferon-
RT inducible protein activator of the 20S proteasome.";
RL FEBS Lett. 366:37-42(1995).
CC -!- FUNCTION: Implicated in immunoproteasome assembly and required for
CC efficient antigen processing. The PA28 activator complex enhances the
CC generation of class I binding peptides by altering the cleavage pattern
CC of the proteasome.
CC -!- SUBUNIT: Heterodimer of PSME1 and PSME2, which forms a hexameric ring.
CC PSME1 can form homoheptamers (By similarity). {ECO:0000250}.
CC -!- INDUCTION: By interferon gamma.
CC -!- SIMILARITY: Belongs to the PA28 family. {ECO:0000305}.
