WebNov 13, 2024 · PERK is composed of an N-terminal luminal domain and a cytosolic effector kinase domain (Fig. 3, A and B) (86, 87). ... likely owing to the difficulty in targeting ATF6 due to its lack of a known enzymatic function or small molecule–binding sites. To confront this challenge, ATF6 activator screens have primarily focused on phenotype-based ... WebFeb 11, 2014 · The small molecule EMD 57033 has been shown to stimulate the actomyosin ATPase activity and contractility of myofilaments. Here, we show that EMD 57033 binds to an allosteric pocket in the myosin motor domain. EMD 57033-binding protects myosin against heat stress and thermal denaturation.

Myosin Summary, Structure, Synthesis, Classes & Role
WebSummary. Myosin is a contractile protein found in the muscles of animals as well as non-muscle cells. It is responsible for muscle contraction as well as intracellular transport. Myosin is made of six subunits including two heavy chains and four light chains. The molecule is considered to be made up of three domains.
