CC -!- FUNCTION: Accepts ubiquitin from the E1 complex and catalyzes its
CC covalent attachment to other proteins. Specifically monoubiquitinates
CC the N-terminus of various substrates, including ATXN3, MAPT/TAU,
CC POLR2H/RPB8 and STUB1/CHIP, by recognizing backbone atoms of disordered
CC N-termini. Involved in degradation of misfolded chaperone substrates by
CC mediating monoubiquitination of STUB1/CHIP, leading to recruitment of
CC ATXN3 to monoubiquitinated STUB1/CHIP, and restriction of the length of
CC ubiquitin chain attached to STUB1/CHIP substrates by ATXN3. After UV
CC irradiation, but not after mitomycin-C (MMC) treatment, acts as a
CC specific E2 ubiquitin-conjugating enzyme for the Fanconi anemia complex
CC by associating with E3 ubiquitin-protein ligase FANCL and catalyzing
CC monoubiquitination of FANCD2, a key step in the DNA damage pathway. In
CC vitro catalyzes 'Lys-11'-linked polyubiquitination. UBE2W-catalyzed
CC ubiquitination occurs also in the presence of inactive RING/U-box type
CC E3s, i.e. lacking the active site cysteine residues to form thioester
CC bonds with ubiquitin, or even in the absence of E3, albeit at a slower
CC rate. {ECO:0000250|UniProtKB:Q96B02}.
CC -!- CATALYTIC ACTIVITY:

CC activating enzyme]-L-cysteine + S-ubiquitinyl-[E2 ubiquitin-
CC conjugating enzyme]-L-cysteine.; EC=2.3.2.23;
CC Evidence={ECO:0000250|UniProtKB:Q96B02, ECO:0000255|PROSITE-
CC ProRule:PRU00388};
CC -!- CATALYTIC ACTIVITY:
