Overview
MAG 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. Binds to RTN4R. Belongs to the immunoglobulin superfamily. SIGLEC (sialic acid binding Ig-like lectin) family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Cell adhesion; Membrane protein, integral
Cellular Component: paranode region of axon; integral to membrane; plasma membrane
Biological Process: substantia nigra development; nerve growth factor receptor signaling pathway; negative regulation of axonogenesis; blood coagulation; cell adhesion; regulation of axonogenesis; leukocyte migration
Reference #:  P20916 (UniProtKB)
Alt. Names/Synonyms: GMA; MAG; myelin associated glycoprotein; Myelin-associated glycoprotein; S-MAG; sialic acid binding Ig-like lectin 4A; sialic acid-binding immunoglobulin-like lectin 4A; Siglec-4a; SIGLEC4A
