RNF126 (Ring Finger Protein 126) is a member of the RING-finger E3 ubiquitin ligase family, characterized by a conserved C3H2C3-type RING domain at its N-terminus, which facilitates substrate ubiquitination by recruiting E2 ubiquitin-conjugating enzymes. This 464-amino acid protein also contains an acidic region and a disordered C-terminal domain, contributing to its interactions with diverse cellular partners. Primarily localized to the cytoplasm and endosomal membranes, RNF126 plays critical roles in membrane trafficking, protein quality control, and DNA damage response. It promotes ubiquitin-dependent sorting of transmembrane proteins, such as EGFR, through the endosomal pathway, regulating their degradation or recycling. Additionally, RNF126 interacts with the BARD1/BRCA1 complex, facilitating homology-directed DNA repair by ubiquitinating damaged chromatin. Dysregulation of RNF126 is implicated in cancer progression, with studies showing both oncogenic and tumor-suppressive effects depending on context. Overexpression in breast and lung cancers correlates with chemoresistance and poor prognosis, while its loss may impair DNA repair, promoting genomic instability. Emerging evidence also links RNF126 to neurodegenerative diseases via its role in clearing misfolded proteins. Despite its multifunctionality, precise molecular mechanisms and tissue-specific regulatory networks remain under active investigation, highlighting its potential as a therapeutic target.
