NCBI Protein Information
NAC (No Apical Meristem) domain transcriptional regulator superfamily protein
NCBI Summary
NAC-domain protein. Involved in root cap development. Involved in a regulatory feedback loop with FEZ. FEZ activates SMB in hte root cap daughter cells soon after division, and SMB in turn represses FEZ expression in these cells, thereby preventing further stem cell divisions.

UniProt Comments
Transcription regulator. Together with BRN1 and BRN2, regulates cellular maturation of root cap. Represses stem cell-like divisions in the root cap daughter cells, and thus promotes daughter cell fate. Inhibits expression of its positive regulator FEZ in a feedback loop for controlled switches in cell division plane. Promotes the expression of genes involved in secondary cell walls (SCW) biosynthesis.
