Summary: Enables actin binding activity and adenylate cyclase binding activity. Involved in several processes, including actin filament depolymerization; positive regulation of mitochondrial fission; and regulation of actin polymerization or depolymerization. Located in actin cortical patch. Used to study ovary epithelial cancer. Orthologous to human CAP1 (cyclase associated actin cytoskeleton regulatory protein 1) and CAP2 (cyclase associated actin cytoskeleton regulatory protein 2).

What's a GeneRIF?

Cyclase-associated protein (CAP) and Cofilin synergize to processively depolymerize actin filament pointed ends at a rate 330-fold faster than spontaneous depolymerization. Single molecule imaging further reveals that hexameric CAP molecules interact with the pointed ends of Cofilin-decorated filaments for several seconds at a time, removing approximately 100 actin subunits per binding event.

Title: Srv2/CAP is required for polarized actin cable assembly and patch internalization during clathrin-mediated endocytosis.
Data show that Twinfilin and Srv2 proteins accelerate depolymerization from actin filament ends.
Title: High-speed depolymerization at actin filament ends jointly catalysed by Twinfilin and Srv2/CAP.
Data indicate that the combined activities of cofilin and Srv2/CAP lead to enhanced filament severing and support an emerging view that actin disassembly is controlled not by cofilin alone, but by a more complex set of factors working in concert.
Title: Srv2/cyclase-associated protein forms hexameric shurikens that directly catalyze actin filament severing by cofilin.
Data suggest a revised model for the mechanism by which Srv2 promotes actin turnover, in which coordinated activities of its N- and C-terminal halves catalyze sequential steps in recycling cofilin and actin monomers.
