A number of ELISA Kits are available that target Ntsr3, an alias of the protein, sortilin 1. The human protein, encoded by the gene SORT1, is a member of the VPS10-related sortilin family, SORT1 subfamily. The protein's cellular localization is indicated to be nuclear and membrane-associated. Additional synonyms or past names for this protein may include: Gp95, LDLCQ6, NT3, NTR3. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog, Chicken.
