Recombinant Human F-actin-capping protein subunit beta (CAPZB)

Uniprot Id

P47756

Target Species

Human

Target Name

CAPZB

Target Full Name

F-actin-capping protein subunit beta

Target Function

F-actin-capping proteins bind in a Ca(2+)-independent manner to the fast growing ends of actin filaments (barbed end) thereby blocking the exchange of subunits at these ends. Unlike other capping proteins (such as gelsolin and severin), these proteins do not sever actin filaments. Plays a role in the regulation of cell morphology and cytoskeletal organization.

Target Subcellular Location

Cytoplasm, cytoskeleton. Cytoplasm, myofibril, sarcomere.

Target Background

This gene encodes the beta subunit of the barbed-end actin binding protein, which belongs to the F-actin capping protein family. The capping protein is a heterodimeric actin capping protein that blocks actin filament assembly and disassembly at the fast growing (barbed) filament ends and functions in regulating actin filament dynamics as well as in stabilizing actin filament lengths in muscle and nonmuscle cells. A pseudogene of this gene is located on the long arm of chromosome 2. Multiple alternatively spliced transcript variants encoding different isoforms have been found.
