Generic protein structure example

Spatacsin is a protein that in humans is encoded by the SPG11 gene.[1][2][3]

Function

Spatacsin, in combination with the SPG15 protein, attaches the AP5 adaptor complex to the outside of late Endosomes or Lysosomes when the protein via which it binds is in a particular state.[4]

Pathology

Mutations of the SPG11 gene cause a rare form of spastic paraplegia, spastic paraplegia type 11.
