Description
Catalogue Number AB6017
Description Anti-F-actin-capping protein subunit beta Antibody
Alternate Names
  • capping protein (actin filament) muscle Z-line, beta
  • F-actin capping protein beta subunit
Background Information F-actin-capping-protein subunit beta (CapZ beta) belongs to the F-actin capping protein family, which are characteristic heterodimers, consisting of an α subunit (31-36 kDa) and a β subunit (28-32 kDa), that cap the barbed end of actin filaments within all eukaryotes. Their ability to bind the actin filaments is in a manner independent of Ca2++ and requires the C-terminal end of both subunits for optimal binding. F-actin capping protein subunit beta is contained within the Z-discs of striated muscle, where it functions to inhibit the polymerization and depolymerization of actin. Within vertebrates, there are three isoforms for each of F-actin capping protein subunit beta’s subunits. While there is almost nothing known regarding the β3 subunit, the β1 and β2 isoforms each have distinct roles. The isoform β2 is predominantly expressed in non-muscle cells and is found in intercalated discs and the cell periphery, but is not observed at Z-discs. Isoform β1 is more greatly expressed in striated muscle and is localized at the Z-discs. It also contains the COOH-terminal extension necessary for capping the actin.

Entrez Gene Number
Entrez Gene Summary CAPZB is a member of the F-actin capping protein family. This gene encodes the beta subunit of the barbed-end actin binding protein. The protein regulates growth of the actin filament by capping the barbed end of growing actin filaments. [provided by RefSeq].
Gene Symbol
  • CAPZ
  • CAPPB
  • CAPB
  • Cap Z
  • CapZ beta
  • CAZB
Purification Method Protein A Purfied
UniProt Number
UniProt Summary FUNCTION: F-actin-capping proteins bind in a Ca2+-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.

SUBUNIT STRUCTURE: Heterodimer of an alpha and a beta subunit. Interacts with ARHGAP17 and RCSD1/CAPZIP. Component of the WASH complex, composed of F-actin-capping protein subunit alpha (CAPZA1, CAPZA2 or CAPZA3), F-actin-capping protein subunit beta (CAPZB), WASH (WASH1, WASH2P, WASH3P, WASH4P, WASH5P or WASH6P), FAM21 (FAM21A, FAM21B or FAM21C), KIAA1033, KIAA0196 and CCDC53.

SUBCELLULAR LOCATION: Cytoplasm › cytoskeleton (By similarity).

SEQUENCE SIMILARITIES: Belongs to the F-actin-capping protein beta subunit family.
Molecular Weight ~ 34 kDa observed MW. There are 3 isoforms produced by alternative splicing: Isoform 1 at 31 kDa, Isoform 2 at 31 kDa, and Isoform 3 (sequence not available).
