  REMARK    IMPRINTING, TISSUE SPECIFICITY, INDUCTION, FUNCTION, AND
            INTERACTION WITH ERD15/CID1; CID7; CID8 AND CID12.
COMMENT     [FUNCTION] Encodes almost entirely the C-terminal domain of
            poly(A)-binding proteins (PABPs). Plays a role in normal seed
            development and growth. {ECO:0000269|PubMed:18796636}.
            [SUBUNIT] Interacts with ERD15/CID1, CID7, CID8 and CID12.
            {ECO:0000269|PubMed:18796636}.
            [TISSUE SPECIFICITY] Mainly expressed in flower buds and in
            siliques containing developing seeds.
            {ECO:0000269|PubMed:18796636}.
            [DEVELOPMENTAL STAGE] Expressed in the central cell before
            fertilization and in the endosperm of seeds from the time of
            fertilization.
            [INDUCTION] In vegetative tissues, expression is repressed by MET1.
            In the endosperm, the maternal MPC allele is activated by DME and
            the paternal MPC allele is repressed by MET1.
            {ECO:0000269|PubMed:18796636}.
            [MISCELLANEOUS] The MPC locus is imprinted. Only the maternal
            inherited allele is expressed in endosperm.
