PSMA3 Antibody (Phospho-Ser250)

Product Specifications

CAS Number

9007-83-4

Gene Name

Proteasome subunit alpha 3

Gene Aliases

HC8, PSC3

Gene ID

5684; 19167; 29670

Reactivity

Human, Mouse, Rat

Immunogen

Synthesized peptide derived from human 20S Proteasome Alpha3 around the phosphorylation site of S250. Location: 190-270aa.

Target

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.
