– TMED4, also known as ERS25, belongs to the EMP24/GP25L family. TMED4 may play a role in the regulation of heat-shock response and apoptosis. It is involved in vesicular protein trafficking, mainly in the early secretory pathway. TMED4 may also play a role in the biosynthesis of secreted cargo including processing. It functions in the regulation of heat-shock response and apoptosis. TMED4 also is involved in endoplasmic reticulum stress response. TMED4 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 20.7 kDa and the accession number is Q7Z7H5-1.
