Enables RAGE receptor binding activity; identical protein binding activity; and metal ion binding activity. Involved in several processes, including long-term synaptic potentiation; negative regulation of skeletal muscle cell differentiation; and positive regulation of myelination. Located in cytoplasm and extracellular space. Used to study demyelinating disease. Biomarker of several diseases, including bipolar disorder; borna disease; brain disease (multiple); mental depression; and sleep apnea. Human ortholog(s) of this gene implicated in Alzheimer's disease; Parkinson's disease; aspergillosis; and schizophrenia. Orthologous to human S100B (S100 calcium binding protein B).
