FUNCTION: E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N-terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation. May be involved in pancreatic homeostasis. Binds leucine and is a negative regulator of the leucine-mTOR signaling pathway, thereby controlling cell growth. {ECO:0000269|PubMed:15548684, ECO:0000269|PubMed:16311597, ECO:0000269|PubMed:20298436, ECO:0000269|PubMed:20835242}.
