CC -!- FUNCTION: Adhesion molecule that mediates interactions between
CC myelinating cells and neurons by binding to neuronal sialic acid-
CC containing gangliosides and to the glycoproteins RTN4R and RTN4RL2
CC (PubMed:8995428, PubMed:9298990). Not required for initial myelination,
CC but seems to play a role in the maintenance of normal axon myelination.
CC Protects motoneurons against apoptosis, also after injury; protection
CC against apoptosis is probably mediated via interaction with neuronal
CC RTN4R and RTN4RL2. Required to prevent degeneration of myelinated axons
CC in adults; this probably depends on binding to gangliosides on the axon
CC cell membrane (By similarity). Negative regulator of neurite outgrowth;
CC in dorsal root ganglion neurons the inhibition is mediated primarily
CC via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via
CC binding to neuronal gangliosides (PubMed:17640868). In cerebellar
CC granule cells the inhibition is mediated primarily via binding to
CC neuronal gangliosides (PubMed:17640868). In sensory neurons, inhibition
CC of neurite extension depends only partially on RTN4R, RTN4RL2 and
CC gangliosides (PubMed:19367338). Inhibits axon longitudinal growth
CC (PubMed:9298990). Inhibits axon outgrowth by binding to RTN4R (By
CC similarity). Preferentially binds to alpha-2,3-linked sialic acid
CC (PubMed:8995428). Binds ganglioside Gt1b (PubMed:8995428).
CC {ECO:0000250|UniProtKB:P20917, ECO:0000269|PubMed:17640868,
CC ECO:0000269|PubMed:19367338, ECO:0000269|PubMed:8995428,
CC ECO:0000269|PubMed:9298990}.
CC -!- SUBUNIT: Monomer and homodimer (By similarity). Interacts (via the
CC first three N-terminal Ig-like domains) with RTN4R and RTN4RL2
CC (PubMed:19420245). Interacts with isoform 2 of BSG (By similarity).
CC {ECO:0000250|UniProtKB:P20917, ECO:0000269|PubMed:19420245}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:16998591,

CC IsoId=P07722-2; Sequence=VSP_002529, VSP_002530;
CC -!- TISSUE SPECIFICITY: Detected in myelin (PubMed:17640868). Detected in
CC olfactory bulb and throughout the brain (at protein level)
CC (PubMed:4020419). Detected in brain (PubMed:2432614).
CC {ECO:0000269|PubMed:2432614, ECO:0000269|PubMed:4020419}.
CC -!- DOMAIN: The C-terminal cytoplasmic region found only in isoform L-MAG
CC is required for normal myelination in the central nervous system (CNS),
CC but is apparently not required for normal myelination in the peripheral
CC nervous system (PNS). {ECO:0000250|UniProtKB:P20917}.
CC -!- DOMAIN: The extracellular domain is required to protect against axon
CC degeneration (By similarity). The first three Ig-like domains mediate
CC interaction with RTN4R and RTN4RL2, but are not sufficient to inhibit
CC neurite outgrowth (PubMed:19420245). The two C-terminal extracellular
CC Ig-like C2-type domains are required for inhibition of axon
CC longitudinal growth (PubMed:9298990, PubMed:19420245, PubMed:19367338).
CC Besides, the two C-terminal extracellular Ig-like C2-type domains are
CC required for protection against apoptosis after nerve injury (By
CC similarity). {ECO:0000250|UniProtKB:P20917,
CC ECO:0000269|PubMed:19367338, ECO:0000269|PubMed:19420245,

CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:P20916}.
CC -!- PTM: Phosphorylated on tyrosine residues.
CC {ECO:0000269|PubMed:16998591}.
CC -!- PTM: Ubiquitinated, leading to proteasomal degradation.
CC {ECO:0000250|UniProtKB:P20917}.
CC -!- SIMILARITY: Belongs to the immunoglobulin superfamily. SIGLEC (sialic
CC acid binding Ig-like lectin) family. {ECO:0000305}.
