Septins are highly conserved GTP-binding proteins that assemble as monomers into hetero-oligomeric complexes and higher-order structures, including filaments and rings, that can associate with membranes and the cytoskeleton. Cell cortex Actin-rich network that is attached to the inner face of the plas...
The cytoskeleton of the eukaryotic cell is made of proteins that give shape to it. The three types of protein that help in the organization of the cell are microtubules, intermediate filaments, and microfilaments. This cytoskeleton is absent in the bacteria. Tubulin is present in the microtubules...
The sensing, integrating, and coordinating features of the eukaryotic cells are achieved by the complex ultrastructural arrays and multifarious functions of the cytoskeleton, including the microtubule network. Microtubules play crucial roles achieved by their decoration with proteins/enzymes as well as by ...
Plant cells are eukaryotic cells, that are found in green plants, photosynthetic eukaryotes of the kingdom Plantae which means they have a membrane-bound nucleus. They have a variety of membrane-bound cell organelles that perform various specific functions to maintain the normal functioning of the ...
Cytoskeleton Thecytoskeletonextends from the nucleus to the cell membrane and is composed of interlocking proteins. In eukaryotic cells, the cytoskeleton includes three main structures: Microtubules Microfilaments Intermediate filaments Lesson Quiz Course ...
Actin is a central component of the eukaryotic cytoskeleton; actin polymerisation and depolymerisation together with cargo-carrying myosins ‘walking’ on polymerised actin tracks form the basis for many cellular functions such as locomotion, cell shape maintenance, vesicular trafficking, gene regulation...

What is the function of the mitochondria in the eukaryotic cell? What are the main functions of the smooth endoplasmic reticulum? What is the function of the cell membrane? What is the function of the amnion? What are the functions of the cytoskeleton?
Microtubules are core components of the eukaryotic cytoskeleton with essential roles in cell division, shaping, motility and intracellular transport. Despite their functional heterogeneity, microtubules have a highly conserved structure made from almost identical molecular building blocks: the tubulin proteins....
Microtubules, a major component of cytoskeletons are comprised of α/β-tubulin heterodimers that form a tubular structure in eukaryotic cells. Microtubules are highly dynamic and constantly undergo polymerization and depolymerization to perform their diverse functions, including intracellular transport, cell...
