Summaries for MBL2 Gene

Entrez Gene Summary for MBL2 Gene

  • This gene encodes the soluble mannose-binding lectin or mannose-binding protein found in serum. The protein encoded belongs to the collectin family and is an important element in the innate immune system. The protein recognizes mannose and N-acetylglucosamine on many microorganisms, and is capable of activating the classical complement pathway. Deficiencies of this gene have been associated with susceptibility to autoimmune and infectious diseases. [provided by RefSeq, Jul 2008]

GeneCards Summary for MBL2 Gene

MBL2 (Mannose Binding Lectin 2) is a Protein Coding gene. Diseases associated with MBL2 include Mannose-Binding Lectin Deficiency and Pulmonary Tuberculosis. Among its related pathways are Toll-like Receptor Signaling Pathway and Creation of C4 and C2 activators. Gene Ontology (GO) annotations related to this gene include calcium ion binding and calcium-dependent protein binding. An important paralog of this gene is SFTPD.

UniProtKB/Swiss-Prot for MBL2 Gene

  • Calcium-dependent lectin involved in innate immune defense. Binds mannose, fucose and N-acetylglucosamine on different microorganisms and activates the lectin complement pathway. Binds to late apoptotic cells, as well as to apoptotic blebs and to necrotic cells, but not to early apoptotic cells, facilitating their uptake by macrophages. May bind DNA.

Variants for MBL2 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for MBL2 Gene

Genetic variations in MBL2 influence susceptibility to hepatitis B virus (HBV) infection [MIM:610424].
Genetic variations in MBL2 are responsible for mannose-binding protein deficiency [MIM:614372]. This condition is defined as MBL2 protein level of less than 100 ng/ml, is present in about 5% of people of European descent and in about 10% of sub-Saharan Africans. Most MBL2-deficient adults appear healthy, but low levels of MBL2 are associated with increased risk of infection in toddlers, in cancer patients undergoing chemotherapy, and in organ-transplant patients receiving immunosuppressive drugs, particularly recipients of liver transplants. There is an association between low levels of MBL2 and a defect of opsonization which results in susceptibility to frequent and chronic infections (PubMed:1675710). Functional MBL2 deficiency may be associated with protection against tuberculosis caused by Mycobacterium africanum but not by Mycobacterium tuberculosis, as observed in studies on Ghanaian patients with pulmonary tuberculosis (PubMed:21695215).
