Transmembrane emp24 domain-containing protein 1

Potential role in vesicular protein trafficking, mainly in the early secretory pathway. May act as a cargo receptor at the lumenal side for incorporation of secretory cargo molecules into transport vesicles and may be involved in vesicle coat formation at the cytoplasmic side. Plays a positive role in IL-33-mediated IL-8 and IL-6 production by interacting with interleukin-33 receptor IL1RL1. Also plays a role in the modulation of innate immune signaling through the cGAS-STING pathway by interacting with RNF26.
