Web15 mrt. 2004 · Through redox regulation of the actin cytoskeleton controls the intracellular distribution of secretory vesicles containing L1/neurofascin/NgCAM family proteins in … Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 … Meer weergeven Actin's primary role in the cell is to form linear polymers called microfilaments that serve various functions in the cell's structure, trafficking networks, migration, and replication. The multifaceted role of actin relies … Meer weergeven Actin filaments are often rapidly assembled and disassembled, allowing them to generate force and support cell movement. Assembly classically occurs in three steps. First, the "nucleation phase", in which two to three G-actin molecules slowly join … Meer weergeven Actin and closely related proteins are present in all organisms, suggesting the common ancestor of all life on Earth had actin. Actin … Meer weergeven Actin is used in scientific and technological laboratories as a track for molecular motors such as myosin (either in muscle tissue or outside it) and as a necessary component for cellular … Meer weergeven Monomeric actin, or G-actin, has a globular structure consisting of two lobes separated by a deep cleft. The bottom of the cleft … Meer weergeven Although most yeasts have only a single actin gene, higher eukaryotes, in general, express several isoforms of actin encoded by a family of related genes. Mammals have at least six actin isoforms coded by separate genes, which are divided into three … Meer weergeven The majority of mammals possess six different actin genes. Of these, two code for the cytoskeleton (ACTB and ACTG1) while the other four are involved in skeletal striated muscle (ACTA1), smooth muscle tissue (ACTA2), intestinal muscles (ACTG2) and Meer weergeven
