NCBI Protein Information
myb-like HTH transcriptional regulator family protein
NCBI Summary
Encodes a MYB-domain protein involved in specification of the leaf proximodistal axis. Mutation results in lobed and dissected leaves with a characteristic asymmetry. Homologous to the Antirrhinum PHANTASTICA (PHAN) and maize ROUGH SHEATH2 (RS2) genes Asymmetric placement of auxin response at the distal leaf tip precedes visible asymmetric leaf growth. Acts alongside AXR1 to exclude BP expression in leaves and with PIN1 to repress BP and promote lateral organ growth. Interacts physically with AS2 to form a complex that binds to the BP promoter and silences BP. Also functions as a regulator of the plant immune response.

UniProt Comments
Transcription factor required for normal cell differentiation. Positively regulates LATERAL ORGAN BOUNDARIES (LOB) within the shoot apex, and the class III HD-ZIP genes REV, PHB, and PHV. Interacts directly with ASYMMETRIC LEAVES 2 (LBD6/AS2) to repress the knox homeobox genes BP/KNAT1, KNAT2, and KNAT6 and the abaxial determinants ARF3/ETT, KAN2 and YAB5. May act in parallel with the RDR6-SGS3-AGO7 pathway, an endogenous RNA silencing pathway, to regulate the leaf morphogenesis (PubMed:11076771, PubMed:11140682, PubMed:11882937, PubMed:12750468, PubMed:16006579, PubMed:16699177, PubMed:17395603, PubMed:17559509, PubMed:23271976). Binds directly to KNAT1, KNAT2, and KNATM chromatin, regulating leaf development (PubMed:23271976). LBD6 is required for this binding (PubMed:23271976). Positive regulator of flowering that binds to the promoter of FT (PubMed:21950734). Regulates FT expression by forming a functional complex with CO (PubMed:21950734).
