Overview
|
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.

Molecular Function
|
Leucine binding; Ubiquitin-protein transferase activity; ligase activity; Zinc ion binding
|
Subcellular Location
|
Cytosol
|
Expression
|
Broadly expressed, with highest levels in skeletal muscle, kidney and pancreas. Present in acinar cells of the pancreas (at protein level).
|
Structure
|
The RING-H2 zinc finger is an atypical RING finger with a His ligand in place of the fourth Cys of the classical motif.
The UBR-type zinc finger forms a pocket that mediates recognition of type 1 N-degrons. It exhibits preference for Arginine in first position, has poor affinity for histidine, and doesn't bind acetylated peptides.
