Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| comment | FUNCTION E3 ubiquitin-protein ligase involved in Golgi membrane fusion and regulation of small GTPases (PubMed:15254018, PubMed:21988917, PubMed:22036506, PubMed:37537642, PubMed:38332367). Acts as a regulator of Golgi membrane dynamics during the cell cycle: recruited to Golgi membrane by Rab proteins and regulates postmitotic Golgi membrane fusion (PubMed:21988917). Acts by mediating ubiquitination during mitotic Golgi disassembly, ubiquitination serving as a signal for Golgi reassembly later, after cell division (PubMed:21988917). Specifically binds GTP-bound RAC1, mediating ubiquitination and subsequent degradation of active RAC1, thereby playing a role in host defense against pathogens (PubMed:22036506, PubMed:37537642, PubMed:38332367). May also act as a transcription regulator via its interaction with RARB (By similarity).CATALYTIC ACTIVITY S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.ACTIVITY REGULATION Sterically autoinhibited in its dimeric state.PATHWAY Protein modification; protein ubiquitination.SUBUNIT Homodimer (PubMed:37537642, PubMed:38332367). The homodimer is autoinhibited and stabilized by its N-terminal helix (PubMed:37537642, PubMed:38332367). Interacts with RAB1 (RAB1A, RAB1B or RAB1C), RAB4 (RAB4A or RAB4B) and RAB11 (RAB11A or RAB11B); in a GTP-dependent manner (PubMed:21988917). Interacts with the 26S proteasomal complex through the 20S core proteasomal subunit (PubMed:15254018). Interacts with RARB (By similarity).INTERACTION A significant portion localizes to the endoplasmic reticulum. Targeted to Golgi membrane via its interaction with Rab proteins.ALTERNATIVE PRODUCTS Expressed in multiple tissues including heart, brain and kidney.DEVELOPMENTAL STAGE Expressed in fetal and pediatric kidney cells.INDUCTION Down-regulated in sporadic Wilms tumor.DOMAIN The N-terminal lobe of the HECT domain is important for interaction with E2 ubiquitin-conjugating enzymes.DOMAIN The ANK repeats ANK 3, ANK 4 and ANK 5 are important for recognizing the RAC1 substrate.PTM Autoubiquitinated.DISEASE Defects in HACE1 are a cause of Wilms tumor (WT). WT is a pediatric malignancy of kidney and one of the most common solid cancers in childhood. HACE1 is epigenetically down-regulated in sporadic Wilms tumor. Moreover, a t(5;6)(q21;q21) translocation that truncates HACE1 has been found in a child with bilateral, young-onset Wilms tumor (PubMed:19948536).DISEASE The disease is caused by variants affecting the gene represented in this entry.SEQUENCE CAUTION Extended N-terminus.SEQUENCE CAUTION Truncated N-terminus.SEQUENCE CAUTION Truncated N-terminus.SEQUENCE CAUTION Truncated N-terminus. |
