Tropomyosin - Specific Roles and Functions - Influencing Binding of Actin Binding Proteins To Actin Filaments
... The actin microfilment system is the fundamental cytoskeletal system involved in the development and maintenance of cell morphology ... Within humans there are only six actin isoforms and these isoforms are responsible for an array of unique and complex cellular structures and key cellular interactions ... It is thought that the function and form of the actin cytoskeleton is largely controlled by actin-binding proteins (ABP) that are associated with the actin polymer ...
CAPG
153615 MGI 1098259 HomoloGene 37523 GeneCards CAPG Gene Gene Ontology Molecular function • actin binding Cellular component • nucleus • nucleolus • cytoplasm • F-actin capping protein ... This gene encodes a member of the gelsolin/villin family of actin-regulatory proteins ... The encoded protein reversibly blocks the barbed ends of F-actin filaments in a Ca2+ and phosphoinositide-regulated manner, but does not sever preformed actin filaments ...
Clostridium Difficile Toxin B - Function - Effects On Small GTPases - Disturbance On Signal Pathways
... cellular regulation of Rho, Rac, and Cdc42 has effects outside the vicinity of the actin filaments of the cytoskeleton (Fig ... Some physiological parts of the cells that are not involved in actin filaments, may not cause cell rounding or cell death right away, but in downstream pathway ... This was an independent event from disruption of the actin cytoskeleton ...
Sliding Filament Model - Process of Movement
... Chains of actin proteins form high tensile passive 'thin' filaments that transmit the force generated by myosin to the ends of the muscle ... Myosin also forms 'thick' filaments ... Each myosin 'paddles' along an actin filament repeatedly binding, ratcheting and letting go, sliding the thick filament over the thin filament ...
Cofilin - Function
... Cofilin is a ubiquitous actin-binding factor required for the reorganization of actin filaments ... ADF/Cofilin family members bind G-actin monomers and depolymerize actin filaments through two mechanisms severing and increasing the off-rate for actin monomers from the pointed end ... "Older" ADP/ADP-Pi actin filaments free of tropomyosin and proper pH are required for cofilin to function effectively ...
