  • Official Full Name

    ubiquitin-like modifier activating enzyme 1

  • Overview

    Ubiquitin-activating enzymes, also known as E1 enzymes, catalyze the first step in the ubiquitination reaction, which targets a protein for degradation via a proteasome. This covalent attachment of ubiquitin or ubiquitin-like proteins to targeted proteins is a major mechanism for regulating protein function in eukaryotic organisms. Many processes such as cell division, immune responses and embryonic development are also regulated by post-transcriptional modification by ubiquitin and ubiquitin-like proteins.
