Gadzira shanduro yakaoma zvikuru yemutsara uyu Actin ipuroteni yeglobular (~ 43 kDa) iyo polymerizes kuumba chimiro chefilament iyo ine maviri actin protofilaments akaputira mumwe nemumwe.
Chokwadi, shanduro yakaoma kunzwisisa yemutsara uyu ndeyekuti "Actin ipuroteni yebhora (~ 43 kDa) iyo polymerizes uye inoumba muchimiro chakarongeka chefilament chine maprotofilament maviri akaputirwa mumwe nemumwe, kuti aumbe 'actin filament' imwechete (yaimbozivikanwa se' microfilament '). "
