CC -!- FUNCTION: May act as a transcriptional regulator involved in the
CC differentiation of young endothelium. Altered differentiation results
CC in incompetence for pigments synthesis and the lack of condensed
CC tannins in the seed coat (PubMed:21477081). Plays a role in the
CC regulatory network controlling flavonoid accumulation in endothelium
CC cells during seed development (PubMed:21477081).
CC {ECO:0000269|PubMed:11782451, ECO:0000269|PubMed:21477081}.
CC -!- SUBUNIT: Can form homodimers. Interacts with MYB75, TT2 and TT16.
CC {ECO:0000269|PubMed:21477081}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:11782451,
CC ECO:0000269|PubMed:20541552, ECO:0000269|PubMed:21477081}.
CC -!- TISSUE SPECIFICITY: Restricted to the endothelium, the innermost cell
CC layer of the seed coat and detected to a lesser extent in the other
CC cell layers of the testa. {ECO:0000269|PubMed:11782451}.
CC -!- DEVELOPMENTAL STAGE: Developing ovules and young seeds.
CC {ECO:0000269|PubMed:11782451}.
CC -!- DISRUPTION PHENOTYPE: Lack of flavanoid pigment accumulation in the
CC seed coat endothelium (transparent testa phenotype).
CC {ECO:0000269|PubMed:21477081}.
CC -!- SIMILARITY: Belongs to the WIP C2H2-type zinc-finger protein family.
CC {ECO:0000305}.
