PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a single ER-luminal thioredoxin-like domain, which, in contrast with similar domains in other PDIs, is mainly oxidized in living cells
	a Trx-like domain that faced the ER lumen, with N-glycosylation site
	an RQR motif in the TMX4 cytosolic domain was reported to be essential for its ER localization because the deletion of RQR motif caused the transport of TMX4 to the cell surface
	a typical C-terminal di-lysine retrieval signal, in the cytosol
	the cytoplasmic tail has a conserved di-arginine motif of the RXR type

text	integral to membrane

	N-glycosylated type I membrane protein that localizes to the ER
	localize to the ER
	MFSD10, TMX4, and ARL6IP6 likely residing in the inner nuclear membrane

basic FUNCTION	acting as a redox-active center
	N-glycosylated type I membrane protein that localizes to the ER
	could work as a reductase in the environment of the ER
	role of TMX4 may be to enable protein folding in cooperation with these proteins consisting of folding complex in the ER
	involved in productive folding together with calnexin and PDIA3
	would be a reductase in the ER
