Transcription activator that plays a role in the regulation of cell expansion in developing leaves (PubMed:26036253). Component of a network formed by the microRNA396 (miRNA396), the GRFs and their interacting factors (GIFs) acting in the regulation of meristem function and the transition between cell division and cell expansion in growing leaves (PubMed:26036253). Interacts with GIF1. Highly expressed in developing leaves. The QLQ domain and WRC domain may be involved in protein-protein interaction and DNA-binding, respectively. Belongs to the GRF family.
