Summaries for SEC23B Gene

Entrez Gene Summary for SEC23B Gene

  • The protein encoded by this gene is a member of the SEC23 subfamily of the SEC23/SEC24 family, which is involved in vesicle trafficking. The encoded protein has similarity to yeast Sec23p component of COPII. COPII is the coat protein complex responsible for vesicle budding from the ER. The function of this gene product has been implicated in cargo selection and concentration. Multiple alternatively spliced transcript variants have been identified in this gene. [provided by RefSeq, Feb 2010]

GeneCards Summary for SEC23B Gene

SEC23B (Sec23 Homolog B, Coat Complex II Component) is a Protein Coding gene. Diseases associated with SEC23B include Dyserythropoietic Anemia, Congenital, Type Ii and Cowden Disease. Among its related pathways are Normal wtCFTR traffic / ER-to-Golgi and Regulation of cholesterol biosynthesis by SREBP (SREBF). An important paralog of this gene is SEC23A.

UniProtKB/Swiss-Prot for SEC23B Gene

  • 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).

  • 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:0000269 PubMed:19561605, ECO:0000269 PubMed:19621418}. Note=The disease is caused by mutations affecting the gene represented in this entry.
