Document Summary
Ch 2 (q 1(abc), 2(abc), 3, 4, 19b) Structural proteins in cells: globular proteins, membrane proteins & transport. Websites on the slide --> good resource for searching up proteins, incl ones covered today. Lecture 5/12 - intro to proteins and protein structure. Actin filaments: in muscle for movement, but found everywhere like rbc. Discoid shape is due to cytoskeleton: microfilaments, intermediate filaments, all of the above make up the cytoskeleton inside the cell. The cytoskeleton: the small green circles are individual actin subunits. They combine to form f-actin --> a filament of actin: microtubules: made up of tubulin proteins, there are proteins that move along these cytoskeleton highways to transport proteins, intermediate filaments: polymers come to form these filaments. Can carry neurotransmitters and more --> these are called motor proteins. Actin filaments: involved in cell division also, actin is a single protein (374 aa) forming a globular structure (g-actin)
