| 英文名称 | Recombinant Human PTPRS Protein, N-His |
| 英文别名 | R-PTP-S; PTPRS; Receptor-type tyrosine-protein phosphatase S; R-PTP-sigma; Receptor-type tyrosine-protein phosphatase sigma |
| 性状 | Lyophilized |
| 纯化方法 | AC |
| 理论分子量 | 35 kDa |
| 储存液 | Lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1mM EDTA, 4% Trehalose, 1% Mannitol. |
| 研究领域 | Neuroscience > Neurology process > Neurogenesis Signal Transduction > Protein Phosphorylation > Tyrosine Phosphatases |
| 亚基 | Interacts with PPFIA1, PPFIA2 and PPFIA3. |
| 亚细胞定位 | Membrane; Single-pass type I membrane protein. |
| 组织特异性 | Detected in all tissues tested except for placenta and liver. |
| 翻译后修饰 | A cleavage occurs, separating the extracellular domain from the transmembrane segment. This process called 'ectodomain shedding' is thought to be involved in receptor desensitization, signal transduction and/or membrane localization. |
| 相似性 | Belongs to the protein-tyrosine phosphatase family. Receptor class 2A subfamily. Contains 8 fibronectin type-III domains. Contains 3 Ig-like C2-type (immunoglobulin-like) domains. Contains 2 tyrosine-protein phosphatase domains. |
| 功能 | Interacts with LAR-interacting protein LIP.1. |
| 保存条件 | Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for frequent use. Store at -20 to -80°C for twelve months from the date of receipt. |
| 注意事项 | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
| 背景资料 | Protein tyrosine phosphatases, or PTPs, are type I transmembrane proteins, membrane associated proteins or proteins localized in nuclei. Examples of transmembrane PTPs are LAR, PTP alpha, PTP beta, PTP gamma, PTP delta, PTP epsilon, PTP zeta, PTP thet, PTP upsilon and PTPs. Transmembrane PTPsigma play diverse roles during development and in adult tissues. Immunodepletion studies have suggested LAR to be a regulator of insulin receptor phosphorylation. PTP alpha activity is increased twofold in response to phorbol ester stimulation, resulting in serine phosphorylation either directly or indirectly by members of the PKC family. Overexpression of v-H-Ras and Neu, but not Myc or Int2, in mammary tumors has been shown to induce PTPe expression. An alternative splicing event leads to a nervous tissue-specific chondroitin sulfate proteoglycan called phosphacan, which represents the amino terminal portion of PTP omega. PTP thet and PTP?share a conserved amino terminal 160 amino acid MAM domain which facilitates homophilic binding. PTP upsilon localizes to points of cell contact and may be involved in regulating the assembly and disassembly of cadherin/catenin complexes in vivo. PTPsigma contains an extracellular region, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus represents a receptor-type PTP. PTPsigma may also be involved in the molecular control of adult nerve repair. Four alternatively spliced transcript variants, which encode distinct proteins, have been reported. |
