Enables
This protein enables 3 target(s):
| Target | Category | Definition |
|---|
| carboxypeptidase activity | molecular function | Catalysis of the hydrolysis of a single C-terminal amino acid residue from a polypeptide chain. [https://www.ebi.ac.uk/merops/about/glossary.shtml#CARBOXYPEPTIDASE] |
| serine-type carboxypeptidase activity | molecular function | Catalysis of the hydrolysis of a single C-terminal amino acid residue from the C-terminus of a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine). [https://www.ebi.ac.uk/merops/about/glossary.shtml#CARBOXYPEPTIDASE] |
| enzyme activator activity | molecular function | Binds to and increases the activity of an enzyme. [GOC:dph, GOC:mah, GOC:tb] |
Located In
This protein is located in 8 target(s):
| Target | Category | Definition |
|---|
| extracellular region | cellular component | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators] |
| lysosome | cellular component | A small lytic vacuole that has cell cycle-independent morphology found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions. [GOC:mah, ISBN:0198506732] |
| endoplasmic reticulum | cellular component | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). [ISBN:0198506732] |
| membrane | cellular component | A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |
| azurophil granule lumen | cellular component | The volume enclosed by the membrane of an azurophil granule, a primary lysosomal granule found in neutrophil granulocytes that contains a wide range of hydrolytic enzymes and is released into the extracellular fluid. [GOC:bf, PMID:17152095] |
| lysosomal lumen | cellular component | The volume enclosed within the lysosomal membrane. [GOC:jl, PMID:15213228] |
| intracellular membrane-bounded organelle | cellular component | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. [GOC:go_curators] |
| extracellular exosome | cellular component | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

Involved In
This protein is involved in 5 target(s):
| Target | Category | Definition |
|---|
| proteolysis | biological process | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. [GOC:bf, GOC:mah] |
| intracellular protein transport | biological process | The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell. [GOC:mah] |
| regulation of protein stability | biological process | Any process that affects the structure and integrity of a protein, altering the likelihood of its degradation or aggregation. [GOC:dph, GOC:mah, GOC:tb] |

| negative regulation of chaperone-mediated autophagy | biological process | Any process that stops, prevents or reduces the frequency, rate or extent of chaperone-mediated autophagy. [GO_REF:0000058, GOC:pad, GOC:PARL, GOC:TermGenie, PMID:20176123] |
