RT Arabidopsis, encodes the conserved C-terminal domain of polyadenylate
RT binding proteins.";
RL Plant Cell 20:2387-2398(2008).
CC -!- FUNCTION: Encodes almost entirely the C-terminal domain of poly(A)-
CC binding proteins (PABPs). Plays a role in normal seed development and
CC growth. {ECO:0000269|PubMed:18796636}.
CC -!- SUBUNIT: Interacts with ERD15/CID1, CID7, CID8 and CID12.
CC {ECO:0000269|PubMed:18796636}.
CC -!- TISSUE SPECIFICITY: Mainly expressed in flower buds and in siliques
CC containing developing seeds. {ECO:0000269|PubMed:18796636}.
CC -!- DEVELOPMENTAL STAGE: Expressed in the central cell before fertilization
CC and in the endosperm of seeds from the time of fertilization.
CC -!- INDUCTION: In vegetative tissues, expression is repressed by MET1. In
CC the endosperm, the maternal MPC allele is activated by DME and the
CC paternal MPC allele is repressed by MET1.
CC {ECO:0000269|PubMed:18796636}.
CC -!- MISCELLANEOUS: The MPC locus is imprinted. Only the maternal inherited
CC allele is expressed in endosperm.
