SBP domains (for SQUAMOSA-pROMOTER BINDING PROTEIN) are found in plant proteins. It is a sequence specific DNA-binding domain [1]. Members of family probably function as transcription factors involved in the control of early flower development [1]. The domain contains 10 conserved cysteine and histidine residues that probably are zinc ligands.	Domain
