General description
Proteasome (prosome, macropain) subunit, α type, 1 (PSMA1), a T1A family peptidase, is an α subunit of the complex 20S core structure of the proteosome, a multicatalytic proteinase complex.
Specificity
Anti-PSMA1 polyclonal antibody reacts with bovine, human, mouse, rat, chicken, zebrafish, and canine proteasome (prosome, macropain) subunit, α type, 1 proteins.
Immunogen
Synthetic peptide directed towards the C terminal region of human PSMA1
Application
Anti-PSMA1 polyclonal antibody is used to tag pregnancy specific proteasome (prosome, macropain) subunit, α type, 1 for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles proteasome (prosome, macropain) subunit, α type, 1 in proteasome structure and function.
Biochem/physiol Actions
The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides.

This gene encodes a member of the peptidase T1A family, that is a 20S core alpha subunit. Two alternative transcripts encoding different isoforms have been identified.The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure.
