Summary
MGRN1 (mahogunin ring finger 1, HGNC:20254) is a protein-coding gene on chromosome 16p13.3, encoding E3 ubiquitin-protein ligase MGRN1 (O60291). E3 ubiquitin-protein ligase.
Enables ubiquitin-protein transferase activity. Involved in endosome to lysosome transport; negative regulation of adenylate cyclase-activating G protein-coupled receptor signaling pathway; and protein monoubiquitination. Located in several cellular components, including early endosome; endoplasmic reticulum; and nucleus.

Literature-anchored findings (GeneRIF, showing 13)
- a role for Mahogunin in a proteasome-independent ubiquitylation pathway: TSG101 is a specific Mahogunin substrate (PMID:17229889)
- Study shows that both (Ctm)PrP and cyPrP can interact with and disrupt the function of Mahogunin (Mgrn), a cytosolic ubiquitin ligase whose loss causes spongiform neurodegeneration. (PMID:19524515)
- It therefore seems probable that the role of MGRN1 in the adrenal relates to the trafficking and/or degradation of the melanocortin 2 receptor. (PMID:21862608)
- data suggest that MGRN1 selectively targets misfolded proteins for degradation and may exhibit viable therapeutic potential for the treatment of spongiform neurodegeneration (PMID:23756845)
- Mahogunin-mediated alpha-tubulin ubiquitination via noncanonical K6 linkage regulates microtubule stability and mitotic spindle orientation. (PMID:24556679)
- Catalytic inactivation of MGRN1 results in elevated levels of GP78 and a consequential increase in the initiation of mitophagy. (PMID:26743086)
- Hypomethylation of CpG sites in RPTOR, MGRN1 and RAPSN in blood is associated with breast cancer. (PMID:27577081)
- Regulation of Mfn1 by MGRN1 and the proteasome modulates mitochondrial fusion. (PMID:27713096)
- With aging, the neuroprotective e3 ligase MGRN1 relocates from the cytosol to the nucleus of neurons, where it associates with chromatin and potentiates the cellular response to proteotoxic stress. This nuclear shift is due to a proteasome impairment dependent increase of a monoubiquitinated form of MGRN1. (PMID:28475871)
- epletion of MGRN1 activity may hamper physiologically important processes like mitochondrial movement in neuronal processes and intracellular transport of ligands through the endosomal pathway thereby contributing to the pathogenesis of neurodegeneration in certain types of prion diseases (PMID:28902452)
- In a heterologous expression system, MC1R-dependent Arrestins B ubiquitination was enhanced by overexpression of MGRN1 and was impaired by siRNA-mediated MGRN1 knockdown thus pointing to MGRN1 as the responsible E3-ligase. (PMID:28947386)
- Mahogunin Ring Finger 1 regulates pigmentation by controlling the pH of melanosomes in melanocytes and melanoma cells. (PMID:34921635)
- MGRN1 depletion promotes intercellular adhesion in melanoma by upregulation of E-cadherin and inhibition of CDC42. (PMID:38008393)

UniProt curated annotations — full annotation on UniProt →
Function. E3 ubiquitin-protein ligase. Mediates monoubiquitination at multiple sites of TSG101 in the presence of UBE2D1, but not of UBE2G1, nor UBE2H. Plays a role in the regulation of endosome-to-lysosome trafficking. Impairs MC1R- and MC4R-signaling by competing with GNAS-binding to MCRs and inhibiting agonist-induced cAMP production. Does not inhibit ADRB2-signaling. Does not promote MC1R ubiquitination. Acts also as a negative regulator of hedgehog signaling.
Subunit / interactions. Interacts with MC1R and MC4R, but not with TBXA2R. Interacts with TSG101. Interacts with mislocalized cytosolically exposed PRNP; this interaction alters MGRN1 subcellular location and causes lysosomal enlargement.
Subcellular location. Early endosome Cytoplasm. Cytosol. Nucleus Cytoplasm. Cell membrane Cytoplasm. Cell membrane.
Post-translational modifications. Autoubiquitinated in vitro.
Domain organisation. The RING finger is required for ubiquitin ligase activity.
Pathway. Protein modification; protein ubiquitination.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 83 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
