This gene encodes an E3 ubiquitin-protein ligase that belongs to the family of HECT (homologous to the E6-accessory protein C-terminus)-type ligases involved in the degradation of proteins via the ubiquitin-proteasome pathway. Members of this family are characterized by a C-terminal HECT domain that catalyses the transfer of ubiquitin to protein substrates and an N-terminal domain that determines the substrate specificity. The HECT domain is bilobal, with one lobe serving as a binding site for E2 ubiquitin-conjugated enzyme and the other lobe containing the catalytic cysteine residue that receives ubiquitin from the E2 enzyme to form a thioester-linked E3-ubiquitin complex required for protein ubiquitination. The encoded protein mediates the ubiquitination of multiple target substrates and plays a key role in epithelial sodium transport by regulating the cell surface expression of the epithelial sodium channel, ENaC. Single nucleotide polymorphisms in this gene may be associated with essential hypertension. Polymorphisms in this gene associated with pulmonary hypertension in sickle cell patients. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
