Protein Structure

UniProt Annotation

Function

Component of the COPII coat, that covers ER-derived vesicles involved in transport from the endoplasmic reticulum to the Golgi apparatus. COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the Golgi complex (By similarity). {ECO:0000250}.

Subcellular Localization

Golgi apparatus membrane {ECO:0000250}. Endoplasmic reticulum membrane {ECO:0000250}. Endoplasmic reticulum-Golgi intermediate compartment membrane {ECO:0000250}.

Disease Associations

Anemia, congenital dyserythropoietic, 2 (CDAN2) [MIM:224100]: An autosomal recessive blood disorder characterized by morphological abnormalities of erythroblasts, ineffective erythropoiesis, normocytic anemia, iron overload, jaundice, and variable splenomegaly. Ultrastructural features include bi- or multinucleated erythroblasts in bone marrow, karyorrhexis, and the presence of Gaucher-like bone marrow histiocytes. The main biochemical feature of the disease is defective glycosylation of some red blood cells membrane proteins. {ECO:0000269PubMed:19561605, ECO:0000269PubMed:19621418}. Note=The disease is caused by mutations affecting the gene represented in this entry.
