NEDD8-activating enzyme E1 catalytic subunit is a protein that in humans is encoded by the UBA3 gene .[5] [6]
The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. This gene encodes a member of the E1 ubiquitin-activating enzyme family. The encoded enzyme associates with AppBp1, an amyloid beta precursor protein binding protein, to form a heterodimer, and then the enzyme complex activates NEDD8, a ubiquitin-like protein , which regulates cell division, signaling and embryogenesis. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.[6]
This enzyme contains an E2 binding domain , which resembles ubiquitin , and recruits the catalytic core of the E2 enzyme UBE2M (Ubc12) in a similar manner to that in which ubiquitin interacts with ubiquitin binding domains .[7]
Interactions [ edit ] UBE1C has been shown to interact with NEDD8 ,[8] APPBP1 [9] UBE2M .[7]
