Protein
F-actin-capping protein subunit alpha
Organism
Caenorhabditis elegans
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.
Similarity
Belongs to the F-actin-capping protein alpha subunit family.
