The DBB domain is named from the Drosophila (Downstream of FGFR - Dof, also known as Heartbroken or Stumps) protein, the BANKS and BCAP, both signalling in B-cell pathway, proteins. This domain defines a minimal region required for mediating Dof dimerisation. Since this domain can interact both with itself and with a region in the C-terminal part of the molecule, it may mediate either intermolecular or intramolecular interactions [1]. Mutants lacking this domain disrupt FGFR signal transduction and fibroblast growth-factor signalling [2]. The DBB domain of BCAP mediates BCAP TIR dimerization and negatively regulates TLR signalling [3].	Domain
