Nexin
Encyclopedia
Nexin is a proteinous inter-doublet linkage that prevents microtubule
s in the outer layer of axoneme
s from movement with respect to each other. Otherwise vesicular transport protein
s such as dynein
would dissolve the whole structure.
Microtubule
Microtubules are a component of the cytoskeleton. These rope-like polymers of tubulin can grow as long as 25 micrometers and are highly dynamic. The outer diameter of microtubule is about 25 nm. Microtubules are important for maintaining cell structure, providing platforms for intracellular...

Axoneme
Numerous eukaryotic cells carry whip-like appendages whose inner core consists of a cytoskeletal structure called the axoneme....
s from movement with respect to each other. Otherwise vesicular transport protein
Vesicular transport protein
A vesicular transport protein is a transmembrane or membrane associated protein. It regulates or facilitates the movement by vesicles of the contents of the cell.-Types:Examples include:* Archain* ARFs* Clathrin* Caveolin...
s such as dynein
Dynein
Dynein is a motor protein in cells which converts the chemical energy contained in ATP into the mechanical energy of movement. Dynein transports various cellular cargo by "walking" along cytoskeletal microtubules towards the minus-end of the microtubule, which is usually oriented towards the cell...
