Enables

This protein enables 4 target(s):

TargetCategoryDefinition
beta-glucuronidase activitymolecular functionCatalysis of the reaction: a beta-D-glucuronoside + H2O = an alcohol + D-glucuronate. [EC:3.2.1.31]
protein bindingmolecular functionBinding to a protein. [GOC:go_curators]
heparanase activitymolecular functionCatalysis of the cleavage of heparan sulfate; can degrade both heparan sulfate and heparin glycosaminoglycan chains. [PMID:10916150]
syndecan bindingmolecular functionBinding to syndecan, an integral membrane proteoglycan (250-300 kDa) associated largely with epithelial cells. [GOC:go_curators, PMID:9355727]

Located In

This protein is located in 9 target(s):

TargetCategoryDefinition
extracellular regioncellular componentThe 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]
nucleuscellular componentA membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]
nucleoplasmcellular componentThat part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
lysosomecellular componentA 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]
lysosomal membranecellular componentThe lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm. [GOC:ai]
specific granule lumencellular componentThe volume enclosed by the membrane of a specific granule, a granule with a membranous, tubular internal structure, found primarily in mature neutrophil cells. Most are released into the extracellular fluid. Specific granules contain lactoferrin, lysozyme, vitamin B12 binding protein and elastase. [GOC:bf, PMID:7334549]
lysosomal lumencellular componentThe volume enclosed within the lysosomal membrane. [GOC:jl, PMID:15213228]
intracellular membrane-bounded organellecellular componentOrganized 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]
membrane raftcellular componentAny of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions. [PMID:16645198, PMID:20044567]

Active In

This protein is active in 2 target(s):

TargetCategoryDefinition
extracellular spacecellular componentThat part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. [ISBN:0198547684]
extracellular matrixcellular componentA structure lying external to one or more cells, which provides structural support, biochemical or biomechanical cues for cells or tissues. [GOC:BHF, GOC:mah, GOC:rph, NIF_Subcellular:nlx_subcell_20090513, PMID:21123617, PMID:28089324]

positive regulation of blood coagulationbiological processAny process that activates or increases the frequency, rate or extent of blood coagulation. [GOC:mah]
heparan sulfate proteoglycan catabolic processbiological processThe chemical reactions and pathways resulting in the breakdown of proteoglycan containing heparan sulfate, any member of a group of glycosaminoglycans that have repeat units consisting of alternating alpha-(1->4) linked hexuronic acid and glucosamine residues, the former being a mixture of sulfated and nonsulfated D-glucuronic and L-iduronic acids, and the latter being either sulfated or acetylated on its amino group as well as sulfated on one of its hydroxyl groups. [GOC:mah, ISBN:0198506732]
heparin metabolic processbiological processThe chemical reactions and pathways involving heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells. They are similar to heparan sulfates but are of somewhat higher average Mr (6000-20000) and contain fewer N-acetyl groups and more N-sulfate and O-sulfate groups; they may be attached in the same manner to protein, forming proteoglycans. They consist predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues. [GOC:mah, ISBN:0198506732]
