-
Cyclase-associated protein (CAP) is a highly conserved and widely, distributed protein that links the nutritional response signaling to, cytoskeleton remodeling. In yeast, CAP is a component of the adenylyl, cyclase complex and helps to activate the Ras-mediated catalytic cycle of, the cyclase. While the N-terminal domain of CAP (N-CAP) provides a binding, site for adenylyl cyclase, the C-terminal domain (C-CAP) possesses actin, binding activity. Our attempts to crystallize full-length recombinant CAP, from Dictyostelium discoideum resulted in growth of orthorhombic crystals, containing only the N-terminal domain (residues 42-227) due to, auto-proteolytic cleavage. The structure was solved by molecular, replacement with data at 2.2 A resolution. The present crystal structure, allows the characterization of a head-to-tail N-CAP dimer in the, asymmetric unit and a crystallographic side-to-side dimer. Comparison with, previously published structures of N-CAP reveals variable modes of, dimerization of this domain, but the presence of a common interface for, the side-to-side dimer.

Cyclase-associated protein (CAP) is a highly conserved and widely distributed protein that links the nutritional response signaling to cytoskeleton remodeling. In yeast, CAP is a component of the adenylyl cyclase complex and helps to activate the Ras-mediated catalytic cycle of the cyclase. While the N-terminal domain of CAP (N-CAP) provides a binding site for adenylyl cyclase, the C-terminal domain (C-CAP) possesses actin binding activity. Our attempts to crystallize full-length recombinant CAP from Dictyostelium discoideum resulted in growth of orthorhombic crystals containing only the N-terminal domain (residues 42-227) due to auto-proteolytic cleavage. The structure was solved by molecular replacement with data at 2.2 A resolution. The present crystal structure allows the characterization of a head-to-tail N-CAP dimer in the asymmetric unit and a crystallographic side-to-side dimer. Comparison with previously published structures of N-CAP reveals variable modes of dimerization of this domain, but the presence of a common interface for the side-to-side dimer.
