基因位点
HPSE Gene in genomic location: bands according to Ensembl, locations according to GeneLoc (and/or Entrez Gene and/or Ensembl if different)
通用注释
亚单元:
Heterodimer; heterodimer formation between the 8 kDa and the 50 kDa subunits is required for enzyme activity. Interacts with TF; the interaction, inhibited by heparin, enhances the generation of activated factor X and activates coagulation. Interacts with HRG; the interaction is enhanced at acidic pH, partially inhibits binding of HPSE to cell surface receptors and modulates its enzymatic activity. Interacts with SDC1; the interaction enhances the shedding of SDC1. Interacts with HPSE2.
功能:
Endoglycosidase that cleaves heparan sulfate proteoglycans (HSPGs) into heparan sulfate side chains and core proteoglycans. Participates in extracellular matrix (ECM) degradation and remodeling. Selectively cleaves the linkage between a glucuronic acid unit and an N-sulfo glucosamine unit carrying either a 3-O-sulfo or a 6-O-sulfo group. Can also cleave the linkage between a glucuronic acid unit and an N-sulfo glucosamine unit carrying a 2-O-sulfo group, but not linkages between a glucuronic acid unit and a 2-O-sulfated iduronic acid moiety. It is essentially inactive at neutral pH but becomes active under acidic conditions such as during tumor invasion and in inflammatory processes. Facilitates cell migration associated with metastasis, wound healing and inflammation. Enhances shedding of syndecans, and increases endothelial invasion and angiogenesis in myelomas. Acts as procoagulant by increasing the generation of activation factor X in the presence of tissue factor and activation factor VII. Increases cell adhesion to the extacellular matrix (ECM), independent of its enzymatic activity. Induces AKT1/PKB phosphorylation via lipid rafts increasing cell mobility and invasion. Heparin increases this AKT1/PKB activation. Regulates osteogenesis. Enhances angiogenesis through up-regulation of SRC-mediated activation of VEGF. Implicated in hair follicle inner root sheath differentiation and hair homeostasis.

Lysosome membrane
Peripheral membrane protein
Secreted
Nucleus
Proheparanase is secreted via vesicles of the Golgi. Interacts with cell membrane heparan sulfate proteoglycans (HSPGs). Endocytosed and accumulates in endosomes. Transferred to lysosomes where it is proteolytically cleaved to produce the active enzyme. Under certain stimuli, transferred to the cell surface. Associates with lipid rafts. Colocalizes with SDC1 in endosomal/lysosomal vesicles. Accumulates in perinuclear lysosomal vesicles. Heparin retains proheparanase in the extracellular medium (By similarity).

人乙酰肝素(HPSE)重组蛋白是否是无菌的？
蛋白试剂瓶和蛋白保存液是经过高压灭菌的，但也不能保证蛋白是完全无菌的。如果要求蛋白是无菌的，可以用0.2微米的滤器对蛋白进行过滤。
[2].
人乙酰肝素(HPSE)重组蛋白的保存缓冲液是什么？
纯化后的蛋白保存在PBS（58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.4）里，并往里面加入500mM咪唑和10%甘油。
[3].
怎样确定人乙酰肝素(HPSE)重组蛋白的浓度？
蛋白浓度的确定没有一个统一的标准，这主要取决于蛋白的氨基酸序列。伊艾博是根据不同测试的组合来测定蛋白浓度。考马斯亮蓝法、BCA法、氨基酸序列和氨基酸全序列分析法等都用来测定蛋白浓度。
[4].
人乙酰肝素(HPSE)重组蛋白蛋白保存条件是怎样的？
蛋白应保存在 -20℃或 -80℃条件下，为了避免反复冻融，可以将蛋白分装成小份保存。
[5].
人乙酰肝素(HPSE)重组蛋白是否可以用于活体实验？
重组蛋白没有用于任何的活体实验，因此蛋白的活性和半衰期是不确定的。
[6].
人乙酰肝素(HPSE)重组蛋白的保质期是多久？
在适当的保存条件下，从购买之日起蛋白可以稳定保存6-12个月。适当的保存条件是:蛋白保存在-20°C o或 -80℃，保证蛋白的保存浓度高于0.1mg/ml，限制蛋白反复冻融的次数。我们公司常规的质量检测保证所有产品在销售时都有可接受的生物活性。但是我们不能控制终端用户蛋白的保存条件。如果产品在有效期内出现问题，请联系我们的技术支持。

你们蛋白和抗体的报价是怎么样的？
我们将根据你需要的蛋白和抗体的大小进行报价。
[8].
人乙酰肝素(HPSE)重组蛋白是否能够提供蛋白片段？
我们现有的人的蛋白的序列可以有很多。你可以选择你感兴趣的靶向部分，我们将会按您的需求提供蛋白和抗体。
[9].
人乙酰肝素(HPSE)重组蛋白的货期或发货时间一般是多长？
具体指标的货期需要确定。最快一周，最长可能一个月。
