Enables

This protein enables 2 target(s):

Target	Category	Definition
serine-type endopeptidase activity	molecular function	Catalysis of the hydrolysis of internal, alpha-peptide bonds in 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). [GOC:mah, https://www.ebi.ac.uk/merops/about/glossary.shtml#CATTYPE]
protein binding	molecular function	Binding to a protein. [GOC:go_curators]

Located In

This protein is located in 4 target(s):

Target	Category	Definition
Golgi membrane	cellular component	The lipid bilayer surrounding any of the compartments of the Golgi apparatus. [GOC:mah]
endoplasmic reticulum lumen	cellular component	The volume enclosed by the membranes of the endoplasmic reticulum. [ISBN:0198547684]
endoplasmic reticulum membrane	cellular component	The lipid bilayer surrounding the endoplasmic reticulum. [GOC:mah]
Golgi stack	cellular component	The set of thin, flattened membrane-bounded compartments, called cisternae, that form the central portion of the Golgi complex. The stack usually comprises cis, medial, and trans cisternae; the cis- and trans-Golgi networks are not considered part of the stack. [GOC:mah, ISBN:0815316194]

Active In

This protein is active in 2 target(s):

Target	Category	Definition
Golgi membrane	cellular component	The lipid bilayer surrounding any of the compartments of the Golgi apparatus. [GOC:mah]
Golgi apparatus	cellular component	A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. [ISBN:0198506732]

Involved In

This protein is involved in 12 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]
lysosome organization	biological process	A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a lysosome. A lysosome is a cytoplasmic, membrane-bounded organelle that is found in most animal cells and that contains a variety of hydrolases. [GOC:mah]
mitotic G2 DNA damage checkpoint signaling	biological process	A mitotic cell cycle checkpoint that detects and negatively regulates progression through the G2/M transition of the cell cycle in response to DNA damage. [GOC:mtg_cell_cycle, PMID:16299494]
cholesterol metabolic process	biological process	The chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. It is a component of the plasma membrane lipid bilayer and of plasma lipoproteins and can be found in all animal tissues. [ISBN:0198506732]
protein processing	biological process	Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein. [GOC:curators, GOC:jl, GOC:jsg]
endoplasmic reticulum unfolded protein response	biological process	The series of molecular signals generated as a consequence of the presence of unfolded proteins in the endoplasmic reticulum (ER) or other ER-related stress; results in changes in the regulation of transcription and translation. [GOC:mah, PMID:12042763]
membrane protein intracellular domain proteolysis	biological process	The proteolytic cleavage of a transmembrane protein leading to the release of an intracellular domain. [PMID:12808018]
response to endoplasmic reticulum stress	biological process	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stress acting at the endoplasmic reticulum. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen. [GOC:cjm, GOC:mah]
ATF6-mediated unfolded protein response	biological process	The series of molecular signals mediated by the endoplasmic reticulum membrane stress sensor ATF6 (activating transcription factor 6). Begins with activation of ATF6 in response to endoplasmic reticulum (ER) stress, and ends with regulation of a downstream cellular process, e.g. transcription. Under conditions of endoplasmic reticulum stress, ATF6 translocates to the Golgi where it is processed by proteases to release a cytoplasmic domain (ATF6f), which operates as a transcriptional activator of many genes required to restore folding capacity. [GOC:bf, GOC:PARL, PMID:22013210]
regulation of cholesterol biosynthetic process	biological process	Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of cholesterol. [GOC:go_curators]
protein maturation	biological process	Any process leading to the attainment of the full functional capacity of a protein. [GOC:ai]
regulation of vesicle-mediated transport	biological process	Any process that modulates the rate, frequency, or extent of vesicle-mediated transport, the directed movement of substances, either within a vesicle or in the vesicle membrane, into, out of or within a cell. [GOC:dph, GOC:tb]
