Cytoskeleton

A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell.

A sarcomere (Greek sarx "flesh", meros "part") is the basic unit of striated muscle tissue.

The structure, function and dynamic behaviour of the cytoskeleton can be very different, depending on organism and cell type.

A flagellum (/fləˈdʒɛləm/; plural: flagella) is a lash-like appendage that protrudes from the cell body of certain prokaryotic and eukaryotic cells.

Actin is a family of globular multi-functional proteins that form microfilaments.

Tubulin (tubul- + -in) in molecular biology can refer either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily.

In cell biology a centriole is a cylindrical cell structure composed mainly of a protein called tubulin that is found in most eukaryotic cells.

A cilium (Latin for eyelash; the plural is cilia) is an organelle found in eukaryotic cells.

Intermediate filaments (IFs) are cytoskeletal components found in the cells of vertebrate animal species, and perhaps also in other animals, fungi, plants, and unicellular organisms.

Microfilaments, also called actin filaments, are filamentous structures in the cytoplasm of eukaryotic cells and form part of the cytoskeleton.

Muscle contraction is the activation of tension-generating sites within muscle fibers.

Neurofilaments (NF) are the 10 nanometer or intermediate filaments found in neurons.

Septins are a group of GTP-binding proteins found primarily in eukaryotic cells of fungi and animals, but also in some green algae.

The major sperm protein (MSP) is a nematode specific small protein of 126 amino acids with a molecular weight of 14 kDa.

'ENA/VASP Homology proteins' or 'EVH' proteins are a family of closely related proteins involved in cell motility in vertebrate and invertebrate animals.

In molecular biology, the protein domain, Stathmin is a crucial protein that regulates the cell cytoskeleton.

The ERM protein family consists of three closely related proteins, ezrin, radixin and moesin.
