Involved in the regulation of cell proliferation in developing shoots and leaves (PubMed:24854713). Does not possess transactivation activity (PubMed:24854713). Interacts with GIF1. Highly expressed in shoots (Ref.1, PubMed:24854713). Expressed in developing leaves (Ref.1, PubMed:24854713). The QLQ domain and WRC domain may be involved in protein-protein interaction and DNA-binding, respectively. Plants over-expressing GRF10 exhibit reduced leaf size and plant height. Belongs to the GRF family. Lacks the whole C-terminal region found in the GRF family, and therefore lacks transactivation activity.
