background | Siglec-4a, also known as Myelin-Associated Glycoprotein (MAG), is a type I transmembrane glycoprotein belonging to the Siglec family, a subgroup of the Ig superfamily. Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2. |
molecular weight | The protein has a predicted MW of 56 kDa. Due to glycosylation, the protein migrates to 70-85 kDa based on Tris-Bis PAGE result. |
available size | 100 µg, 500 µg |
endotoxin | Less than 1EU per μg by the LAL method. |

Function Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2 (PubMed:12089450, PubMed:27922006, PubMed:7533044). Not required for initial myelination, but seems to play a role in the maintenance of normal axon myelination (PubMed:10625334, PubMed:7516497, PubMed:9262180, PubMed:9469574, PubMed:9482781, PubMed:9482783). Protects motoneurons against apoptosis, also after injury; protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2 (PubMed:26335717). Required to prevent degeneration of myelinated axons in adults; this probably depends on binding to gangliosides on the axon cell membrane (PubMed:15953602, PubMed:19158290). Negative regulator of neurite outgrowth that inhibits axon longitudinal growth (PubMed:12089450, PubMed:19158290, PubMed:27922006). Negative regulator of neurite outgrowth; in dorsal root ganglion neurons the inhibition is mediated primarily via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via binding to neuronal gangliosides (PubMed:17640868). In cerebellar granule cells the inhibition is mediated via binding to neuronal gangliosides (PubMed:17640868). In sensory neurons, inhibition of neurite extension depends only partially on RTN4R, RTN4RL2 and gangliosides (By similarity). Inhibits axon outgrowth by binding to RTN4R (PubMed:12089450). Preferentially binds to alpha-2,3-linked sialic acid (PubMed:27922006, PubMed:7533044). Binds ganglioside Gt1b (PubMed:27922006). |
Subellular location Cell membrane ; Single-pass type I membrane protein. Membrane raft . |
Tissues Detected in the myelin tract in brain, especially in the corpus callosum and in peripheral nerve (PubMed:24191038, PubMed:7516497, PubMed:9482783). Expressed by myelinating glial cells in the central and peripheral nervous system (PubMed:10625334). Detected in oligodendrocyte processes before formation of compact myelin (PubMed:10625334, PubMed:2474006). Restricted to the periaxonal space after myelination (PubMed:10625334). Isoform S-MAG is the predominant isoform in CNS and PNS of the adult (at protein level) (PubMed:1716323). |
Structure Monomer and homodimer (PubMed:27922006). Interacts (via the first three N-terminal Ig-like domains) with RTN4R and RTN4RL2 (PubMed:12089450, PubMed:26335717). Interacts with isoform 2 of BSG (PubMed:12558975). |
Post-translational modification N-glycosylated.; Phosphorylated on tyrosine residues.; Ubiquitinated, leading to proteasomal degradation. |
