The sensing, integrating, and coordinating features of the eukaryotic cells are achieved by the complex ultrastructural arrays and multifarious functions of the cytoskeletal network. Cytoskeleton comprises fibrous protein networks of microtubules, actin, and intermediate filaments. These filamentous polymer ...
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...
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 ...
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....
What are the functions of the cytoskeleton? What is the main purpose of cell differentiation? What are the functions of epithelial tissue? What is the function of squamous epithelial cells? What is the function of the mitochondria in the eukaryotic cell?
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...
Ribosomes are organelles mediating protein translation, which is one of the most energy-demanding activities within the cell. Generally, eukaryotic ribosomes consist of two subunits, i.e., 40S and 60S subunits, which comprise ribosomal proteins and rRNA [1]. In addition to translation, ribosomal...
The eukaryotic cytoskeleton consists of filaments composed of polymers of actin, tubulin, or intermediate filament proteins. The basic organizational principle of all these filamentous systems is identical: large complex structures are built from small, simpler components — either from multisubunit or fro...
What are the major chemical components of a plant cell wall? What is an important characteristic of the plant cell wall? What are the main functions of a cell membrane? What are the functions of the cytoskeleton? What are three key functions of the prokaryote cell wall?
In living cells, the bulk of Tau protein is attached to microtubules and stabilizes them; hence its role in the microtubule-based cytoskeleton was accepted as the standard Tau function (see also Fig. 1). Note that a non-standard role for Tau in relation to RNA, DNA, or actin binding ...
