Binds to histones H3K4me1, H3K4me2 and H3K4me3 in GST pull-down assay (PubMed:28818372). May facilitate the recruitment of effectors to mediate gene expression (By similarity). Highly expressed in young panicles (PubMed:28818372). Expressed at low levels in leaf sheaths, nodes, internodes and axillary buds (PubMed:28818372). The CW-type zinc finger domain is not required for nuclear localization.
