These proteasome subunit alpha 3 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. proteasome subunit alpha 3 is an alias of the human PSMA3 gene, which encodes the protein, proteasome 20S subunit alpha 3. The protein is a known component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. The PSMA3 protein is 255 amino acid residues in length and 28.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include HC8, PSC3, and proteasome subunit alpha type-3.
