Summaries for CUBN Gene

Entrez Gene Summary for CUBN Gene

  • Cubilin (CUBN) acts as a receptor for intrinsic factor-vitamin B12 complexes. The role of receptor is supported by the presence of 27 CUB domains. Cubulin is located within the epithelium of intestine and kidney. Mutations in CUBN may play a role in autosomal recessive megaloblastic anemia. [provided by RefSeq, Jul 2008]

GeneCards Summary for CUBN Gene

CUBN (Cubilin) is a Protein Coding gene. Diseases associated with CUBN include Megaloblastic Anemia-1, Finnish Type and Megaloblastic Anemia. Among its related pathways are Vitamin digestion and absorption and Diseases of metabolism. GO annotations related to this gene include calcium ion binding and receptor activity. An important paralog of this gene is TLL1.

UniProtKB/Swiss-Prot for CUBN Gene

  • Cotransporter which plays a role in lipoprotein, vitamin and iron metabolism, by facilitating their uptake. Binds to ALB, MB, Kappa and lambda-light chains, TF, hemoglobin, GC, SCGB1A1, APOA1, high density lipoprotein, and the GIF-cobalamin complex. The binding of all ligands requires calcium. Serves as important transporter in several absorptive epithelia, including intestine, renal proximal tubules and embryonic yolk sac. Interaction with LRP2 mediates its trafficking throughout vesicles and facilitates the uptake of specific ligands like GC, hemoglobin, ALB, TF and SCGB1A1. Interaction with AMN controls its trafficking to the plasma membrane and facilitates endocytosis of ligands. May play an important role in the development of the peri-implantation embryo through internalization of APOA1 and cholesterol. Binds to LGALS3 at the maternal-fetal interface.

Defects in vitamin B12 absorption lead to impaired function of thymidine synthase. As a consequence DNA synthesis is interrupted. Rapidly dividing cells involved in erythropoiesis are particularly affected. {ECO:0000269 PubMed:10080186, ECO:0000269 PubMed:10887099}.
