RT early embryogenesis.";

CC -!- FUNCTION: As accessory component of DNA polymerase II participates in
CC chromosomal DNA replication. Required for the timing and determination
CC of cell fate during plant embryogenesis and root pole development, by
CC promoting cell cycle and cell type patterning. Necessary for proper
CC shoot (SAM) and root apical meristem (RAM) functions (By similarity).
CC Is essential to promote the first divisions of the zygote
CC (PubMed:16212602). {ECO:0000250|UniProtKB:F4HW04,
CC ECO:0000269|PubMed:16212602}.
CC -!- SUBUNIT: Subunit of the DNA polymerase II (Probable). Interacts with
CC POL2A (via C-terminus) (PubMed:16212602). {ECO:0000269|PubMed:16212602,
CC ECO:0000305|PubMed:16212602}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- DEVELOPMENTAL STAGE: During plant development, expressed in the shoot
CC and root meristematic regions, but not inthe meristems in seeds at
CC germination nor in trichomes undergoing endoreduplication. During male
CC gametogenesis, transiently expressed in immature pollen grains at the
CC time of post-meiotic mitosis, but not in the female macrospores at any
CC time of development. Expressed in the embryo sac after fertilization
CC and the in the embryo proper and suspensor cells until the globular
CC stage. At the triangular stage, expressed in the forming shoot apical
CC meristem. {ECO:0000269|PubMed:16212602}.
CC -!- INDUCTION: Cell cycle regulated. Up-regulated at the G1/S phase
CC transition and then decreases rapidly as cells progress into S-phase.
CC {ECO:0000269|PubMed:16212602}.
CC -!- DISRUPTION PHENOTYPE: Embryonic lethality when homozygous, due to
CC embryo development arrested at one-cell stage.
CC {ECO:0000269|PubMed:16212602}.
CC -!- SIMILARITY: Belongs to the DNA polymerase epsilon subunit B family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAC34504.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
