Acts as a actin nucleation factor, remains associated with the slow-growing pointed end of the new filament. Involved in vesicle transport processes providing a novel link between actin organization and intracellular transport. Required for localization of determinants within the developing oocyte to the posterior pole and to the dorsal anterior corner. Links Rho family signaling and Jnk function to the actin cytoskeleton.

CAPs are multifunctional proteins that contain several structural domains. CAP is involved in species-specific signalling pathways [, , , ]. In Drosophila, CAP functions in Hedgehog-mediated eye development and in establishing oocyte polarity. In Dictyostelium (slim mold), CAP is involved in microfilament reorganisation near the plasma membrane in a PIP2-regulated manner and is required to perpetuate the cAMP relay signal to organise fruitbody formation. In plants, CAP is involved in plant signalling pathways required for co-ordinated organ expansion. In yeast, CAP is involved in adenylate cyclase activation, as well as in vesicle trafficking and endocytosis. In both yeast and mammals, CAPs appear to be involved in recycling G-actin monomers from ADF/cofilins for subsequent rounds of filament assembly [, ]. In mammals, there are two different CAPs (CAP1 and CAP2) that share 64% amino acid identity. All CAPs appear to contain a C-terminal actin-binding domain that regulates actin remodelling in response to cellular signals and is required for normal cellular morphology, cell division, growth and locomotion in eukaryotes. CAP directly regulates actin filament dynamics and has been implicated in a number of complex developmental and morphological processes, including mRNA localisation and the establishment of cell polarity. Actin exists both as globular (G) (monomeric) actin subunits and assembled into filamentous (F) actin. In cells, actin cycles between these two forms. Proteins that bind F-actin often regulate F-actin assembly and its interaction with other proteins, while proteins that interact with G-actin often control the availability of unpolymerised actin. CAPs bind G-actin. In addition to actin-binding, CAPs can have additional roles, and may act as bifunctional proteins. In Saccharomyces cerevisiae (Baker's yeast), CAP is a component of the adenylyl cyclase complex (Cyr1p) that serves as an effector of Ras during normal cell signalling. S. cerevisiae CAP functions to expose adenylate cyclase binding sites to Ras, thereby enabling adenylate cyclase to be activated by Ras regulatory signals. In Schizosaccharomyces pombe (Fission yeast), CAP is also required for adenylate cyclase activity, but not through the Ras pathway. In both organisms, the N-terminal domain is responsible for adenylate cyclase activation, but the S cerevisiae and S. pombe N-termini cannot complement one another. Yeast CAPs are unique among the CAP family of proteins, because they are the only ones to directly interact with and activate adenylate cyclase []. S. cerevisiae CAP has four major domains. In addition to the N-terminal adenylate cyclase-interacting domain, and the C-terminal actin-binding domain, it possesses two other domains: a proline-rich domain that interacts with Src homology 3 (SH3) domains of specific proteins, and a domain that is responsible for CAP oligomerisation to form multimeric complexes (although oligomerisation appears to involve the N- and C-terminal domains as well). The proline-rich domain interacts with profilin, a protein that catalyses nucleotide exchange on G-actin monomers and promotes addition to barbed ends of filamentous F-actin []. Since CAP can bind profilin via a proline-rich domain, and G-actin via a C-terminal domain, it has been suggested that a ternary G-actin/CAP/profilin complex could be formed. This entry represents the N-terminal domain of CAP proteins. This domain has an all-alpha structure consisting of six helices in a bundle with a left-handed twist and an up-and-down topology [].; GO: 0003779 actin binding, 0007010 cytoskeleton organization; PDB: 1TJF_B 1S0P_A.
