Source	Description
UniProt	Transcriptional activator (PubMed:19717544, PubMed:22974309). Involved in lateral root formation. Regulated by the transcriptional activators ARF7 and ARF19 (PubMed:17259263). Functions in the initiation and emergence of lateral roots, in conjunction with LBD18, downstream of ARF7 and ARF19 (PubMed:19717544, PubMed:23749813). Acts downstream of the auxin influx carriers AUX1 and LAX1 in the regulation of lateral root initiation and development (PubMed:26059335). {ECO:0000269\|PubMed:17259263, ECO:0000269\|PubMed:19717544, ECO:0000269\|PubMed:22974309, ECO:0000269\|PubMed:23749813, ECO:0000269\|PubMed:26059335}.
