background:
CAPZA1 is a member of the F-actin capping protein alpha subunit family. This gene encodes the alpha 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, and has roles in cell motility and actin assembly.
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.
Subunit:
Heterodimer of an alpha and a beta subunit. Interacts with S100A (By similarity). 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. Interacts with S100B.
Subcellular Location:
Cytoplasm, cytoskeleton (By similarity).
Similarity:
Belongs to the F-actin-capping protein alpha subunit family.
