CC -!- FUNCTION: Probable transcription factor that binds to the DNA sequence
CC 5'-GCATTAAATGC-3' (PubMed:16778018). Seems to promote cell
CC differentiation (PubMed:25564655). {ECO:0000269|PubMed:16778018,
CC ECO:0000269|PubMed:25564655}.
CC -!- SUBUNIT: Interacts with AIL7/PLT7. {ECO:0000269|PubMed:25564655}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in cells around the base of leaf
CC primordia, in the outermost 2 to 3 cell layers along the boundary
CC between two leaf primordia. Expressed in lateral root primordia and
CC tips, and in the epidermal boundaries of two cotyledons at heart-stage
CC embryo. {ECO:0000269|PubMed:16778018}.
CC -!- DISRUPTION PHENOTYPE: In plants missing HDG3, HDG7, HDG11, PDF2 and
CC ATML1, increased cell division leading to cell overproliferation.
CC {ECO:0000269|PubMed:25564655}.
CC -!- SIMILARITY: Belongs to the HD-ZIP homeobox family. Class IV subfamily.
CC {ECO:0000305}.
