UBE2U, UBE2U_HUMAN, Ubiquitin carrier protein U, Ubiquitin-conjugating enzyme E2 U, Ubiquitin-protein ligase U.
The ubiquitin (Ub) pathway involves three sequential enzymatic steps that facilitate the conjugation of Ub and Ub-like molecules to specific protein substrates. The first step requires ATP-dependent activation of the Ub C-terminus and assembly of multi-U
