Gigaxonin is a ubiquitously expressed protein encoded by the GAN gene located on human chromosome 16q24.1. 1, 2 The lack or loss of function of gigaxonin causes giant axonal neuropathy (GAN), an autosomal recessive disorder. The GAN gene has more than 50 distinct loss of function mutations that cause the disorder. 3-6 …

WebTheir function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place. Figure 1 shows how intermediate filaments create a supportive scaffolding inside the cell. The intermediate filaments are the most diverse group of cytoskeletal elements. WebThe cytoskeleton is the framework of the cell which forms the structural supporting component. Microtubules are the largest element of the cytoskeleton. The walls of the microtubule are made of polymerized dimers of α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the ...
