description: The lateral organ boundaries (LOB) gene encodes a plant-specific protein of unknown function
  that is expressed at the adaxial base of initiating lateral organs. The N-terminal of the LOB protein
  contains an approximately 100-amino acid conserved domain (the LOB domain) that is present in 42 other
  Arabidopsis thaliana proteins as well as in proteins from a variety of other plant species. The LOB
  domain contains conserved blocks of amino acids that identify the LOB domain (LBD) gene family. In particular,
  a conserved C-x(2)-C-x(6)-C-x(3)-C motif, which is the defining feature of the LOB domain, is present
  in all LBD proteins [[cite:PUB00018358]].
