How do the different structures and properties of myosin II and myosin V reflect their different functions in cells?
Step by step
Solved in 2 steps
- The Arp2/3 complex makes branched actin filaments by associating with a ‘mother’ actin filament and initiating assembly of a ‘daughter’ actin filament. Although it has been thought that Arp2/3 complex associates with and makes branches from the side of the ‘mother’ actin filament, it is alternatively possible that Arp2/3 complex associates with and makes branches from the barbed end of the ‘mother’ actin filament. Design an in vitro experiment (with purified proteins, such as actin and Arp2/3 complex) to determine which of these possibilities is correct by taking advantage of capping protein (binds and blocks barbed ends), and direct visualization of actin filaments. (1) Briefly describe your experiment in no more than three sentences (2) Draw diagrams of what the arrangement of actin filaments (simple lines are okay) are expected to look like in your proposed experimental and control conditions that indicate the possible outcomes of your experiment (3) Briefly describe your…Protein-X has a calcium (Ca²+)-binding regulatory subunit. Upon calcium (Ca²+) binding the protein changes its own conformation resulting in the conformation change of protein-Y. As a result of this calcium (Ca²+)-dependent protein-X mediated conformational change protein-Y exposes the myosin II head binding sites on the skeletal muscle actin filaments. Identify the protein-X and protein-Y from the following choices. O Protein-X: Troponin; Protein-Y: Tropomysosin O Protein-X: Tropomodulin; CapZ O Protein-X: Nebulin; Protein-Y: Titin Protein-X: Tropomysosin; Protein-Y: TropomodulinExplain the basis for coiling of alpha-helices in the tail of myosin and its relationship to the number of amino acids per turn of the alpha helix.

Explain why?After donating its phosphate molecule to adenosine diphosphate (ADP), which compound helps restore creatine phosphate to its original?Why is the proportion of actin within filaments in cells smaller than would be predicted by in vitro experiments?
- What is the repeating sequence of collagen and how is it essential to the structure of the triple coils of collagen fibers?1. Which myosin type II property is most different from kinesin-1? A) myosin has two heads that can bind to cytoskeletal filamentsB) myosin is recruited into thick bipolar assembliesC) myosin hydrolyzes ATPD) myosin is an allosteric motor 2. If you were examining a newly available genome and your task was to identify the encoded family of kinesin motor proteins, what domain would be the most useful starting place for your analysis? A) Light chain #1 binding sitesB) Neck regionC) Cargo domainD) Motor domainE) Light chain #2 binding sites please explainMYK-461 is also hypothesized to a) stabilize a head-head interaction in two-headed cardiac myosin. b) inhibit skeletal muscle myosin shortening. c) prevent myosin binding protein C from regulating actin-activation of cardiac myosin. d) accelerate ADP release, but only in the absence of actin. e) disrupt the OFF state of the thick-filament.

- What is a A collagen gene?You are attempting to crystallize the head group of a myosin-like muscle protein from a newly discovered vertebrate organism. Assuming that the protein structure is similar to other vertebrate myosins, which enzymes should you use to remove the myosin-like head group from the rest of the myosin-like protein? A) both trypsin and myosinase B) both trypsin and papain C) papain D) trypsin E) myosinaseNeurofilament proteins assemble into long, intermediate filaments , found in abundance running along the length of nerve cell axons. The C-terminal region of these proteins is an unstructured polypeptide, hundreds of amino acids long and heavily modified by the addition of phosphate groups. The term “polymer brush” has been applied to this part of the neurofilament. can you suggest why?
