Criteria | CMA | e-MI |
---|---|---|
Half-Life of the substrate | Long Half-life | Long Half-life |
Substrate association with organelle |
CMA active lysosomes | Late endosomes/MVB a |
Interacts with hsc70 through KFERQ-like motif |
Yes | Yes |
Interacts with LAMP2A | Yes | No |
Requires protein substrate unfolding |
Yes | No |
Lumenal delivery |
|
|
Multivesicular bodies;
knock-down,
endosomal sorting complexes required for transport
