Summary

TRIM50 (tripartite motif containing 50, HGNC:19017) is a protein-coding gene on chromosome 7q11.23, encoding E3 ubiquitin-protein ligase TRIM50 (Q86XT4). E3 ubiquitin-protein ligase that ubiquitinates Beclin-1/BECN1 in a ‘Lys-63’-dependent manner enhancing its binding to ULK1.

Enables identical protein binding activity. Predicted to be involved in innate immune response. Predicted to act upstream of or within regulation of establishment of protein localization. Located in cytosol.

All UniProt accessions (1): Q86XT4

UniProt curated annotations — full annotation on UniProt →

Function. E3 ubiquitin-protein ligase that ubiquitinates Beclin-1/BECN1 in a ‘Lys-63’-dependent manner enhancing its binding to ULK1. In turn, promotes starvation-induced autophagy activation. Also interacts with p62/SQSTM1 protein and thereby induces the formation and the autophagy clearance of aggresome-associated polyubiquitinated proteins through HDAC6 interaction. Also promotes NLRP3 inflammasome activation by directly inducing NLRP3 oligomerization independent of its E3 ligase function.

Subunit / interactions. Can form dimers and trimers. Interacts with several E2 ubiquitin-conjugating enzymes, including UBE2L6, UBE2E1, UBE2E3. No interaction with UBE2H. Interacts with BECN1. Interacts with SQSTM1. Interacts with NLRP3.

Subcellular location. Cytoplasm.

Post-translational modifications. Auto-ubiquitinated. Acetylated by EP300 and KAT2B. HDAC6 drives TRIM50 deacetylation. Acetylation antagonizes with TRIM50 ubiquitination.

Similarity. Belongs to the TRIM/RBCC family.
