Anti-PSMB6 antibodies are used in the immunodetection of the protein proteasome 20S subunit beta 6. In humans, the canonical protein has a reported length of 239 amino acid residues and a mass of 25.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. A member of a the Peptidase T1B protein family, PSMB6 is a known component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. Synonyms for this target antigen include LMPY, proteasome subunit beta type-6, PSY large multifunctional protease Y, macropain delta chain, and DELTA.
