CC -!- FUNCTION: E1-like enzyme which specifically catalyzes the first step in
CC ufmylation. Activates UFM1 by first adenylating its C-terminal glycine
CC residue with ATP, and thereafter linking this residue to the side chain
CC of a cysteine residue in E1, yielding a UFM1-E1 thioester and free AMP.
CC Activates UFM1 via a trans-binding mechanism, in which UFM1 interacts
CC with distinct sites in both subunits of the UBA5 homodimer. Trans-
CC binding also promotes stabilization of the UBA5 homodimer, and enhances
CC ATP-binding. Transfer of UFM1 from UBA5 to the E2-like enzyme UFC1 also
CC takes place using a trans mechanism. Ufmylation is involved in
CC reticulophagy (also called ER-phagy) induced in response to endoplasmic
CC reticulum stress (By similarity). Ufmylation is essential for erythroid
CC differentiation of both megakaryocytes and erythrocytes (By
CC similarity). {ECO:0000250|UniProtKB:Q8VE47,
CC ECO:0000250|UniProtKB:Q9GZZ9}.
CC -!- SUBUNIT: Homodimer; homodimerization is required for UFM1 activation.
CC Interacts (via UIS motif) with UFM1; binds UFM1 via a trans-binding
CC mechanism in which UFM1 interacts with distinct sites in both subunits
CC of the UBA5 homodimer. Interacts (via UIS motif) with GABARAPL2 and,
CC with lower affinity, with GABARAP and GABARAPL1. Interacts (via C-
CC terminus) with UFC1. {ECO:0000250|UniProtKB:Q9GZZ9}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9GZZ9}. Nucleus
CC {ECO:0000250|UniProtKB:Q9GZZ9}. Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q9GZZ9}. Golgi apparatus
CC {ECO:0000250|UniProtKB:Q9GZZ9}. Note=Localizes mainly in the cytoplasm,
CC while it localizes to the nucleus in presence of SUMO2. Interaction
CC with GABARAPL2 promotes localization to the endoplasmic reticulum
CC membrane. {ECO:0000250|UniProtKB:Q9GZZ9}.
CC -!- DOMAIN: The UFM1-interacting sequence (UIS) motif mediates interaction
CC with both UFM1 and LC3/GABARAP proteins (GABARAP, GABARAPL1 and
CC GABARAPL2). {ECO:0000250|UniProtKB:Q9GZZ9}.
CC -!- SIMILARITY: Belongs to the ubiquitin-activating E1 family. UBA5
CC subfamily. {ECO:0000305}.
