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. {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 C-terminus) with ufc1.
CC {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}.
CC -!- SIMILARITY: Belongs to the ubiquitin-activating E1 family. UBA5
CC subfamily. {ECO:0000305}.
