Homo sapiens

Also known as GMA; S-MAG; SPG75; SIGLEC4A; SIGLEC-4A

Gene ID: 4099 | Gene type: protein coding

About MAG

Cytogenetic location: 19q13.12 Genomic coordinates (GRCh38): 19:35,292,161-35,313,807 (from NCBI)

This gene has 8 transcripts (splice variants), 182 orthologues, 16 paralogues and is associated with 2 phenotypes. Biased expression in brain (RPKM 53.6) and ovary (RPKM 16.9).

Summary

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]
