Activity summary

The ERI3 protein also known as EC-RNA Interacting Protein 3 functions mechanistically in the processing of RNA. This protein has a molecular mass of approximately 72 kDa. ERI3 expression occurs across several tissues with notable presence in the liver and kidneys. Its role in RNA processing makes it integral to various cellular processes that require accurate RNA management.

Biological function summary

ERI3 decapsulates mRNA influencing mRNA stability and turnover. This function positions ERI3 as essential in mRNA decay mechanisms. ERI3 doesn't work in isolation; it forms part of a multi-protein complex involved in mRNA decay and RNA processing activities. Studies suggest that it interacts directly with other key proteins in these complexes contributing to its biological significance.

Pathways

ERI3 plays a role in RNA degradation and nonsense-mediated mRNA decay pathways. It contributes to these pathways by interacting with proteins such as DCP2 and XRN1 which are important for mRNA turnover. This involvement ensures that cells maintain their mRNA levels and quality affecting overall protein synthesis necessary for cellular function.

Associated diseases and disorders

ERI3 shows a connection to liver cancer where its dysregulation impacts RNA decay processes linked to tumorigenesis. Another disorder associated with ERI3 is hereditary hemochromatosis although the connection is still under exploration. Within liver cancer the protein's relationship with DCP2 may influence disease progression highlighting ERI3's potential as a therapeutic target or biomarker.
