PSA71_DROME - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: PSA71_DROME
• UniProt AC: P22769
• Protein Name: Proteasome subunit alpha type-7-1
• Gene Name: Prosalpha4
• Organism: Drosophila melanogaster (Fruit fly).
• Sequence Length: 249
• Subcellular Localization: Cytoplasm. Nucleus.
• Protein Description: 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..
