They are made out of subunits called tubulin]]> 2016-12-04 02:44:16 UTC https://padlet.com/taylorknapp2/p7zo1p0ddtr8/wish/141574028 taylorknapp2 https://padlet.com/taylorknapp2/p7zo1p0ddtr8/wish/141574046 Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events]]> 2016-12-04 02:45:08 UTC https://padlet.com/taylorknapp2/p7zo1p0ddtr8/wish/141574046 taylorknapp2 https://padlet.com/taylorknapp2/p7zo1p0ddtr8/wish/141574073 Motor proteins utilizing the cytoskeleton for movement fall into two categories based on their substrates: Actin motors such as myosin move along microfilaments through interaction with actin. Microtubule motors such as dynein and kinesin move along microtubules through interaction with tubulin

It functions as a modulator of plasma membrane behavior and cell surface properties]]> 2016-12-04 02:47:14 UTC https://padlet.com/taylorknapp2/p7zo1p0ddtr8/wish/141574082
