UniprotTISSUE SPECIFICITY: Expressed at low levels in stems and siliques, specifically in xylem. {ECO:0000269|PubMed:16581911, ECO:0000269|PubMed:17890373, ECO:0000269|PubMed:9839469}.
Functional Description ? help Back to Top
Source Description
UniProtTranscription activator. Involved in the regulation of secondary wall biosynthesis in fibers and vessels (PubMed:17890373). Transcription activator of the mannan synthase CSLA9 that recognizes and binds to the DNA consensus sequence 5'-[AG][GT]T[AT]GGT[GA]-3' cis-regulatory element of CSLA9 promoter (PubMed:24243147). Transcription factor that acts as molecular switch in the NAC012/SND1-mediated transcriptional network regulating secondary wall biosynthesis. Is directly activated by NAC012/SND1. Functions redundantly with MYB83 in the transcriptional regulatory cascade leading to secondary wall formation in fibers and vessels (PubMed:19808805). Transcription activator that binds to the DNA consensus sequence 5'-ACC[AT]A[AC][TC]-3', designated as the secondary wall MYB-responsive element (SMRE). Regulates directly numerous transcription factors and a number of genes involved in secondary wall biosynthesis that contain SMRE elements in their promoters (PubMed:22197883). Is an obligate component of the transcriptional regulatory complex toward the commitment of secondary wall cellulose synthesis. Is required for functional expression of the three secondary wall CESA genes, CESA4, CESA7 and CESA8 (PubMed:23726771). {ECO:0000269|PubMed:17890373, ECO:0000269|PubMed:19808805, ECO:0000269|PubMed:22197883, ECO:0000269|PubMed:23726771, ECO:0000269|PubMed:24243147}.
