FAM19A5 is a secretory protein that is predominantly expressed in the brain. Although the FAM19A5 gene has been found to be associated with neurological and/or psychiatric diseases, only limited information is available on its function in the brain. FAM19A5 plays a role in nervous system development from an early stage and increases its expression in response to pathological conditions in subsets of neurons and OPCs of the brain. FAM19A5 Protein, Human, Recombinant (His) is expressed in E. coli expression system with N-His tag. The predicted molecular weight is 10.79 kDa and the accession number is Q7Z5A7-2.
