Rnf186 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
RNF186 (RING Finger Protein 186) is an endoplasmic reticulum-anchored E3 ubiquitin ligase with a single transmembrane domain. It is expressed predominantly in the gastrointestinal tract and brain, where it plays roles in protein quality control, lipid metabolism, and cellular stress responses. [1]

The study of Rnf186 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development. [3]
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions. [4]

RNF186 is expressed in various tissues with highest expression in the gastrointestinal tract, liver, and kidney. In the brain, expression is moderate with detection in:
The protein localizes to the endoplasmic reticulum and plasma membrane, consistent with its predicted function in cellular signaling and quality control.
RNF186 is an E3 ubiquitin ligase with a RING finger domain that catalyzes ubiquitin transfer to target proteins. Key functions include:
The enzyme utilizes a RING finger domain to facilitate ubiquitin transfer from E2 conjugating enzymes to substrate proteins.
RNF186 variants have been associated with AD risk through genome-wide studies. Potential mechanisms include:
Evidence suggests RNF186 involvement in PD through:
Given high gastrointestinal expression, RNF186 may play a role in:
| Approach | Strategy | Status |
|---|---|---|
| Small molecule modulators | Enhance/inhibit RNF186 activity | Preclinical |
| Gene therapy | Restore function | Experimental |
| Protein replacement | Extracellular delivery | Theoretical |
