| 产品编号 | bs-2731P |
| 英文名称 | SH2B2 Antibody Blocking Peptide |
| 中文名称 | APS封闭多肽 |
| 英文别名 | APS; Adaptor protein with pleckstrin homology and src homology 2 domains; SH2 and PH domain containing adapter protein APS; SH2B2_HUMAN; SH2B adapter protein 2; Adapter protein with pleckstrin homology and Src homology 2 domains; SH2 and PH domain-containing adapter protein APS. |
| 纯化方法 | HPLC |
| 亚基 | Homodimer. Interacts with KIT/c-KIT, SHC1, EPOR, PDGFR, VAV1 and VAV3. Interacts (via N-terminal region) with SHC1. Interacts (via the phosphorylated C-terminus) with GRB2. Interacts (via its SH2 domain) with EPOR, INSR and KIT. Interacts with GRB2 after B-cell antigen receptor stimulation. Interacts (via PH domain) with VAV3. Interacts with NTRK1, NTRK2 and NTRK3 (phosphorylated); after stimulation of the receptor by its extracellular ligand and subsequent autophosphorylation of the receptor. Binds INSR, GRB2, ASB6 and CAP. Insulin stimulation leads to dissociation of CAP. Binds CBS only when SH2B2/APS has become phosphorylated. INSR binding does not depend on the phosphorylation of SH2B2/APS. |
| 亚细胞定位 | Cytoplasm. Cell membrane. Note=Cytoplasmic before PDGF stimulation. After PDGF stimulation, localized at the cell membrane and peripheral region. |
| 组织特异性 | Expressed in spleen, prostate, testis, uterus, small intestine and skeletal muscle. Among hematopoietic cell lines, expressed exclusively in B-cells. Not expressed in most tumor cell lines. |
| 翻译后修饰 | Tyrosine phosphorylated by JAK2, KIT and other kinases activated by B-cell receptor in response to stimulation with cytokines, IL3, IL5, PDGF, IGF1, IGF2, CSF2/GM-CSF and cross-linking of the B-cell receptor complex. |
| 相似性 | Belongs to the SH2B adapter family. Contains 1 PH domain. Contains 1 SH2 domain. |
| 功能 | Adapter protein for several members of the tyrosine kinase receptor family. Involved in multiple signaling pathways. May be involved in coupling from immunoreceptor to Ras signaling. Acts as a negative regulator of cytokine signaling in collaboration with CBL. Binds to EPOR and suppresses EPO-induced STAT5 activation, possibly through a masking effect on STAT5 docking sites in EPOR. Suppresses PDGF-induced mitogenesis. May induce cytoskeletal reorganization via interaction with VAV3. |
| 保存条件 | Shipped at 4℃. Stored at -20℃ for one year. Avoid repeated freeze/thaw cycles. |
| 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 | The protein encoded by this gene is expressed in B lymphocytes and contains pleckstrin homology and src homology 2 (SH2) domains. In Burkitt's lymphoma cell lines, it is tyrosine-phosphorylated in response to B cell receptor stimulation. Because it binds Shc independent of stimulation and Grb2 after stimulation, it appears to play a role in signal transduction from the receptor to the Shc/Grb2 pathway.
