Previous GeneCards Identifiers for HACE1 Gene
This gene encodes a HECT domain and ankyrin repeat-containing ubiquitin ligase. The encoded protein is involved in specific tagging of target proteins, leading to their subcellular localization or proteasomal degradation. The protein is a potential tumor suppressor and is involved in the pathophysiology of several tumors, including Wilm's tumor. [provided by RefSeq, Mar 2016]
GeneCards Summary for HACE1 Gene
HACE1 (HECT Domain And Ankyrin Repeat Containing E3 Ubiquitin Protein Ligase 1) is a Protein Coding gene. Diseases associated with HACE1 include Spastic Paraplegia And Psychomotor Retardation With Or Without Seizures and Neuroblastoma. Among its related pathways are Class I MHC mediated antigen processing and presentation and Ubiquitin-Proteasome Dependent Proteolysis. Gene Ontology (GO) annotations related to this gene include ligase activity and Rab GTPase binding. An important paralog of this gene is NEDD4.
UniProtKB/Swiss-Prot Summary for HACE1 Gene
E3 ubiquitin-protein ligase involved in Golgi membrane fusion and regulation of small GTPases. 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. Acts by mediating ubiquitination during mitotic Golgi disassembly, ubiquitination serving as a signal for Golgi reassembly later, after cell division. Specifically interacts with GTP-bound RAC1, mediating ubiquitination and subsequent degradation of active RAC1, thereby playing a role in host defense against pathogens. May also act as a transcription regulator via its interaction with RARB.
