Whether to self-degrade is a crucial cellular decision. When nutrients are abundant, degradation of cell components is reduced through inactivation of a protein called TFEB by the enzyme complex mTORC1. The structure of a megacomplex consisting of 36 polypeptide chains, which presents TFEB to mTORC1, has been resolved.
