PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	an adenylation domain
	AAs 364-404 were demonstrated to be necessary for the transthiolation of UFM1 to UFC1
	UBA5 AA 381-404 was identified to be the minimal region for UFC1 recognition
	a C-terminal region

HOMOLOGY

interspecies	homolog to murine Ube1dc1

Homologene

FAMILY	ubiquitin-activating E1 family
	UBA5 subfamily

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,nucleus

basic FUNCTION	may have an oxidoreductase activity and be involved in L-serine biosynthesis
	activate an ubiquitin-like protein, ubiquitin-fold modifier 1 (UFM1), by forming a high-energy thioester bond
	essential role, as a specific activating enzyme for the ubiquitin-like modifier, UFM1, in erythroid development
	dispensable for the production of erythropoietin, but its genetic loss led to impaired development of megakaryocyte and erythroid progenitors from common myeloid progenitors
	smallest ubiquitin-like molecule-activating enzyme
	E1-activating enzyme of ubiquitin-fold modifier 1 (UFM1), a recently identified ubiquitin-like protein
	role of UBA5 dimerization in UFM1 activation

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

aminoacid

signaling

UFM1-UBA5-UFC1 ubiquination pathway

a component

fusion protein between UBA5 381-404 and UFC1 exists as a homodimer in solution

INTERACTION

DNA

RNA

small molecule

protein	activate another ubiquitin-like protein, SUMO2, besides UFM1 (greatly activated SUMO2 in the nucleus or transferred activated-SUMO2 to nucleus after it conjugated SUMO2 in the cytoplasm)
	UFM1 covalently attach with cellular protein(s) via a specific E1-activating enzyme (UBA5) and an E2-conjugating enzyme (UFC1)
	UFM1 is activated by the E1 enzyme UBA5, and this pathway is proposed to play an important role in the endoplasmic reticulum (ER) stress response
	Ufmylation is initiated by UBA5, which activates and transfers UFM1 to ubiquitin-fold modifier-conjugating enzyme 1 (UFC1)
	UBA5 binds to UFM1 via a trans-binding mechanism in which UFM1 interacts with distinct sites in both subunits of the UBA5 dimer
