Document Summary
Cell shape and movement cortical function (near pm) Isoforms : a (globular) t atp binding cleft and ( due to cleft on polymerizes into. Double helix asymmetry shape with and -0 end. Decorate with myosin si binds 1 stabilizes microfilaments. Stop adding monomers use up monomers monomers on/off nuclei added at t -0. Involves hydrolysis no atp form around to add once off) And not capped like mt ( but it could be) : 0. 12 m of atp - g- actin. 0 : 0. 60 uh of atp - g - actin c o! Pol . at of both ends treadmilling. [ g- actin] is 400hm so regulation is critical. Atp - g - actin and provides a reservoir ( functionally removes it) to inhibit polymerization. End specific end blower) if end capped. Can cap both ends to stabilize microfilament size. Phalloidin can be tagged actin actin filaments filaments and used for imaging.
