Summaries for MAG Gene

Entrez Gene Summary for MAG Gene

  • The protein encoded by this gene is a type I membrane protein and member of the immunoglobulin superfamily. It is thought to be involved in the process of myelination. It is a lectin that binds to sialylated glycoconjugates and mediates certain myelin-neuron cell-cell interactions. Three alternatively spliced transcripts encoding different isoforms have been described for this gene. [provided by RefSeq, Nov 2010]

GeneCards Summary for MAG Gene

MAG (Myelin Associated Glycoprotein) is a Protein Coding gene. Diseases associated with MAG include Spastic Paraplegia 75 and Demyelinating Polyneuropathy. Among its related pathways are Cell surface interactions at the vascular wall and Basigin interactions. GO annotations related to this gene include carbohydrate binding. An important paralog of this gene is SIGLEC10.

UniProtKB/Swiss-Prot for MAG Gene

  • Adhesion molecule in postnatal neural development that mediates sialic-acid dependent cell-cell interactions between neuronal and myelinating cells. Preferentially binds to alpha-2,3-linked sialic acid (By similarity).

  • Spastic paraplegia 75, autosomal recessive (SPG75) [MIM:616680]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPG75 is characterized by onset in early childhood and is associated with mild to moderate cognitive impairment. {ECO:0000269 PubMed:24482476, ECO:0000269 PubMed:26179919}. Note=The disease is caused by mutations affecting the gene represented in this entry.
