This is the C-terminal domain of Armadillo-like helical domain- containing protein 3 (ARMH3), the previously uncharacterised peripheral Golgi protein C10orf76. ARMH3 interacts with and is involved in GBF1 recruitment, Golgi maintenance and protein secretion [1]. The function of this domain is unknown.
