CC -!- FUNCTION: Acts as a repressor in the regulation of translation
CC initiation of poly(A)-containing mRNAs. Its inhibitory activity on
CC translation is mediated via its action on PABPC1. Displaces the
CC interaction of PABPC1 with poly(A) RNA and competes with PAIP1 for
CC binding to PABPC1. Its association with PABPC1 results in disruption of
CC the cytoplasmic poly(A) RNP structure organization (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Interacts with the second and third RRM domains and C-terminus
CC regions of PABPC1 in a 2:1 stoichiometry. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- DOMAIN: Only the PABPC1-interacting motif-1 (PAM1) interferes with the
CC binding of PABPC1 to poly(A) RNA and translation initiation.
CC {ECO:0000250}.
CC -!- PTM: Ubiquitinated, leading to its degradation by the proteasome.
CC {ECO:0000250|UniProtKB:Q9BPZ3}.
CC -!- SIMILARITY: Belongs to the PAIP2 family. {ECO:0000305}.
