Annexin VI (AnxVI) from porcine liver, a member of the annexin family of Ca(2+)- and membrane-binding proteins, has been shown to bind ATP in vitro with a K(d) in the low micromolar concentration range. However, this protein does not contain within its primary structure any ATP-binding consensus motifs found in other nucleotide-binding proteins. In addition, binding of ATP to AnxVI resulted in modulation of AnxVI function, which was accompanied by changes in AnxVI affinity to Ca2+ in the presence of ATP. Using limited proteolytic digestion, purification of protein fragments by affinity chromatography on ATP-agarose, and direct sequencing, the ATP-binding site of AnxVI was located in a C-terminal half of the AnxVI molecule. To further study AnxVI-nucleotide interaction we have employed a functional nucleotide analog, Cibacron blue 3GA (CB3GA), a triazine dye which is commonly used to purify multiple ATP-binding proteins and has been described to modulate their activities. We have observed that AnxVI binds to CB3GA immobilized on agarose in a Ca(2+)-dependent manner. Binding is reversed by EGTA and by ATP and, to a lower extent, by other adenine nucleotides. CB3GA binds to AnxVI also in solution, evoking reversible aggregation of protein molecules, which resembles self-association of AnxVI molecules either in solution or on a membrane surface. Our observations support earlier findings that AnxVI is an ATP-binding protein.

Skuodas and Clemons et al. show that protein aggregation is pervasive during early development and that the ABCF family of soluble ATP-binding proteins, which are encoded by animal genomes and expressed embryonically, regulate disaggregation and are instrumental for a normal developmental program.
