May act as a link between DNA replication, transcription and chromatin remodeling during flower development. May participate in the repression of LHP1-targeted genes during flower development by direct interaction with LHP1 (PubMed:26538092). May be involved in the polar growth of plant cells via transportation of RNAs (Probable). Homodimer (PubMed:19795213, PubMed:26538092). Interacts wtih ABAP1, ARIA and LHP1 (PubMed:26538092). Interacts with the non-modified histones H1, H2B, H3 and H4 (PubMed:26538092). A number of isoforms are produced. According to EST sequences. Expressed in roots, leaves, stems and flowers. Expressed during vegetative to reproductive phase of development, with the main expression occurring in early flower development. Plants with reduced expression of DUF7 show a slight delay in flowering.
