Autophagin 4A is an enzyme from the group of cysteine proteases .
properties
Autophagin 4A is produced in many cell types , particularly in the skeletal muscles and the brain . It is involved in transport from the cytosol to vacuoles and in autophagy . Autophagin 4A cuts the C -terminal amino acid of autophagin 8 , which exposes a C -terminal glycine that binds phosphatidylethanolamine and subsequently to a lipid bilayer in the course of autophagy. The preferred substrate for autophagin 4A is GABARAPL2 , followed by MAP1LC3A and GABARAP . It is inhibited by N-ethyl maleimide. Autophagin 4A is redox- regulated; in a reducing environment it is activated, in an oxidizing environment it is inhibited.
