Summary: Enables protein heterodimerization activity. Involved in several processes, including barbed-end actin filament capping; oogenesis; and regulation of plasma membrane bounded cell projection assembly. Part of F-actin capping protein complex. Colocalizes with adherens junction. Is expressed in several structures, including amnioserosa; anterior-posterior subdivision of organism; embryonic/larval hemocyte; embryonic/larval midgut primordium; and gut section. Orthologous to human CAPZB (capping actin protein of muscle Z-line subunit beta). [provided by Alliance of Genome Resources, Dec 2024]

Title: Shaping Drosophila eggs: unveiling the roles of Arpc1 and cpb in morphogenesis.
Data show that actin-capping protein subunits Cpa and Cpb stabilize each other's protein levels and can stimulate the production of each other's mRNA when the level of one of the subunit is reduced.
Title: Subunits of the Drosophila actin-capping protein heterodimer regulate each other at multiple levels.
Data show that the actin-Capping Protein (CP) alphabeta heterodimer, which regulates actin filament (F-actin) polymerization, limits Src-induced apoptosis or tissue overgrowth by restricting JNK activation.
