BIOL 3305 Lecture Notes - Lecture 1: Sliding Filament Theory, Intermediate Filament, Scleroprotein
Document Summary
Initial projection is achieved by actin polymerization. pulled in utilizing motor proteins. Initial part relies on polymerization: design an experiment to determine whether vesicle movement in a cell relies on myosin or kinesin motor proteins. To confirm this, break down microtubules, and if it stop then you know for sure it was kinesin. Staggered arrangement is an intermediate filament: whole range of proteins that can be used to make them. Purpose of the slime, its though to be anti- predator mechanism: what"s interesting about slime, it is a mix of proteins. Two different components, glycoproteins and intermediate filaments: slime glands all down length of fish, one cell produces glycoproteins, and the other type of cell releases a wound up intermediate filament. When the hagfish releases slime, intermediate bundle released with glycoproteins. Mix with seawater and smashing of fish, and intermediate filaments mix with glycoproteins and produce slime.
