The function of septins in cells include serving as a localized attachment site for other proteins, and preventing the diffusion of certain molecules from one cell compartment to another. [36] In yeast cells, they build scaffolding to provide structural support during cell division and compartmentalize parts of the cell.

The cellular cytoskeleton is a dynamic system that functions on many different levels: In addition to giving the cell a particular form and supporting the transport of vesicles and organelles, it can also influence gene expression. The signal transduction mechanisms involved in this communication are little understood.
In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis , a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis , a process ...
This oscillation occurs repeatedly during the cell cycle, thereby keeping MinC (and its septum inhibiting effect) at a lower time-averaged concentration at the middle of the cell than at the ends of the cell. [24] The dynamic behavior of the Min proteins has been reconstituted in vitro using an artificial lipid bilayer as mimic for the cell ...
In neuronal axons, the actin or spectric cytoskeleton forms an array of periodic rings [10] and in the sperm flagellum it forms a helical structure. [11] In plant cells, the cell cortex is reinforced by cortical microtubules underlying the plasma membrane. The direction of these cortical microtubules determines which way the cell elongates when ...
Cytoskeleton-associated protein 5 is a microtubule-associated protein that in humans is encoded by the CKAP5 gene. [ 5 ] [ 6 ] [ 7 ] It is the homolog of the Xenopus protein XMAP215 [ 8 ] and is also known as ch-Tog .
Cytoskeleton-associated protein 4 is a protein that in humans is encoded by the CKAP4 gene. [5] [6]CKAP4 also historically known as CLIMP-63 (cytoskeleton-linking membrane protein 63), or just p63 (during the 1990s) is an abundant type II transmembrane protein residing predominantly in the endoplasmic reticulum (ER) of eukaryotic cells and encoded in higher vertebrates by the gene CKAP4.
