CC -!- FUNCTION: Essential protein. Putative transcription factor.
CC -!- SUBUNIT: Homo or heterodimer. Interacts with ZHD1, ZHD3, ZHD4, ZHD5,
CC ZHD6, ZHD7, ZHD8, ZHD9, ZHD10 and ZHD11. {ECO:0000269|PubMed:16428600}.
CC -!- INTERACTION:
CC Q9SB61; Q9LXG0: ZHD8; NbExp=3; IntAct=EBI-1806256, EBI-1806405;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Mostly expressed in flowers and, to a lower extent,
CC in inflorescence, stems and leaves. {ECO:0000269|PubMed:16428600}.
CC -!- DOMAIN: The homeodomain differs form the typical one by having namely 4
CC instead of 3 extra amino acids inserted in the loop between helix 1 and
CC helix 2.
CC -!- DISRUPTION PHENOTYPE: Arrested at early embryo stages.
CC {ECO:0000269|PubMed:15634699}.
