Figure 2. Identification of 33 Atg proteins.

Figure 2

Currently, there are 33 autophagy-related (Atg) proteins in fungi that have been identified by various screens. Seventeen core Atg proteins are required for all autophagy-related pathways, and most function at the stage of autophagosome formation. Another sixteen proteins have more specific roles. These latter components are typically involved in the induction of particular autophagy-related pathways in response to different physiological conditions and/or the recognition of selective cargos.
