InterPro domain: IPR031421

This family of proteins is found in plants. Proteins in this family are typically between 103 and 140 amino acids in length. There are two conserved sequence motifs: LQRS and FRR.

Proteins containing this domain includes Arabidopsis At1g15400 and At1g80180. At1g80180 is a MAPK kinase substrate that may play a role in the regulation of stomata patterning [ 1 ].
