In budding and fission yeasts the CAP protein is a bifunctional protein whose N-terminal domain binds to adenylyl cyclase, thereby enabling that enzyme to be activated by upstream regulatory signals, such as Ras. The function of the C-terminal domain is less clear, but it is required for normal cellular morphology and growth control [1]. CAP is conserved in higher eukaryotic organisms where its function is not yet clear [2].
Structurally, CAP is a protein of 474 to 551 residues which consist of two domains separated by a proline-rich hinge. We have developed two signature patterns, one corresponds to a conserved region in the N-terminal extremity and the other to a C-terminal region.
