Welcome to SBP !

SQUAMOSA promoter-binding protein (SBP)-box (briefly: SBP) or SBP-like (SPL) genes encode a type of TF family that is uniquely conserved in plants. SBP genes encode a class of proteins that have a conserved DNA-binding domain (SBP-specific domain) that contains about 75 amino acid residues (aa). The SBP-specific domain is sufficient to bind to the GTAC core motif. There are three common structures in all SBP-specific domains: two zinc fingers and a nuclear localization signal (NLS). SBP genes play critical roles in regulating flowering, fruit ripening, phase transition, and other physiological processes.
