Component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. This complex plays numerous essential roles within the cell by associating with different regulatory particles. Associated with two 19S regulatory particles, forms the 26S proteasome and thus participates in the ATP-dependent degradation of ubiquitinated proteins. The 26S proteasome plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins that could impair cellular functions, and by removing proteins whose functions are no longer required. Associated with the PA200 or PA28, the 20S proteasome mediates ubiquitin-independent protein degradation. This type of proteolysis is required in several pathways including spermatogenesis (20S-PA200 complex) or generation of a subset of MHC class I-presented antigenic peptides (20S-PA28 complex).
NCBI and Uniprot Product Information
NCBI Description
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. Three alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Uniprot Description
PSMA4: The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. Belongs to the peptidase T1A family. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The PSMA4 psma4 (Catalog #AAA4752192) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The PSMA4 Rabbit pAb reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's PSMA4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemistry (IHC), Immunocytochemistry (ICC), Immunofluorescence (IF), Immunoprecipitation (IP). WB: 1:1000-1:5000 IHC: 1:100 ICC/IF: 1:100 IP: 1:50. Researchers should empirically determine the suitability of the PSMA4 psma4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "PSMA4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
