This is the healthy helical coil (residues 307-349) of TDP-43. A key biomolecular cause of ALS appears to be a helix-sheet transition in this area, leading to the formation of protein fibrils. '''Tdp-43'''. Click above on '''edit this page''' to modify. Be careful with the &lt; and &gt; signs.

'''Tdp-43''' or '''TAR DNA-binding protein 43''' is a heterogeneous nuclear ribonucleoprotein which has crucial roles in gene expression and alternative splicing, stress response, neuronal functions such as neurite outgrowth and many other cellular processes<ref>PMID:17981595</ref>.
