Anti-SULTX3 antibodies are used in antigen-specific immunodetection in biological samples. The target SULTX3 is a known alias name of the protein sulfotransferase family 4A member 1, encoded by the SULT4A1 gene in humans. This 284-amino acid residue protein is known to be involved in metabolic processes, among other biological processes. It is localized to the cytoplasm of the cell. It is reported to be expressed in the cerebral cortex, cerebellum, and caudate. Other synonyms for SULTX3 include BR-STL-1, BRSTL1, and DJ388M5.3.
