产品介绍background:
The steady state of protein tyrosyl phosphorylation in cells is regulated by the opposing action of tyrosine kinases and protein tyrosine phosphatases (PTPs). Several groups have independently identified a non transmembrane PTP, designated SHPTP1 (also known as PTP1C, HCP and SHP), which is primarily expressed in hematopoietic cells and characterized by the presence of two SH2 domains N terminal to the PTP domain. A second and much more widely expressed PTP with SH2 domains, SHPTP2 (also designated PTP1D and Syp), has been identified. SHP2 is a protein tyrosine phosphatase that is widely expressed and plays a regulatory role in various cell signaling events that are important for many cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration.
Function:
Acts downstream of various receptor and cytoplasmic protein tyrosine kinases to participate in the signal transduction from the cell surface to the nucleus. Dephosphorylates ROCK2 at Tyr-722 resulting in stimulatation of its RhoA binding activity.
Subunit:
Interacts with phosphorylated LIME1 and BCAR3. Interacts with SHB and INPP5D/SHIP1. Interacts with MILR1 (tyrosine-phosphorylated). Interacts with FLT1 (tyrosine-phosphorylated), FLT3 (tyrosine-phosphorylated), FLT4 (tyrosine-phosphorylated), KIT and GRB2. Interacts with PDGFRA (tyrosine phosphorylated). Interacts (via SH2 domain) with TEK/TIE2 (tyrosine phosphorylated) (By similarity). Interacts with PTPNS1 and CD84. Interacts with phosphorylated SIT1 and MPZL1. Interacts with FCRL3, FCRL4, FCRL6 and ANKHD1. Interacts with KIR2DL1; the interaction is enhanced by ARRB2. Interacts with GAB2. Interacts with TERT; the interaction retains TERT in the nucleus. Interacts with PECAM1 and FER. Interacts with EPHA2 (activated); participates in PTK2/FAK1 dephosphorylation in EPHA2 downstream signaling. Interacts with ROS1; mediates PTPN11 phosphorylation. Interacts with PDGFRB (tyrosine phosphorylated); this interaction increases the PTPN11 phosphatase activity.
Subcellular Location:
Cytoplasm.
Tissue Specificity:
Widely expressed, with highest levels in heart, brain, and skeletal muscle.
Post-translational modifications:
Phosphorylated on Tyr-546 and Tyr-584 upon receptor protein tyrosine kinase activation; which creates a binding site for GRB2 and other SH2-containing proteins. Phosphorylated upon activation of the receptor-type kinase FLT3. Phosphorylated upon activation of the receptor-type kinase PDGFRA (By similarity). Phosphorylated by activated PDGFRB.
DISEASE:
Phosphorylated on Tyr-546 and Tyr-584 upon receptor protein tyrosine kinase activation; which creates a binding site for GRB2 and other SH2-containing proteins. Phosphorylated upon activation of the receptor-type kinase FLT3. Phosphorylated upon activation of the receptor-type kinase PDGFRA (By similarity). Phosphorylated by activated PDGFRB.

Belongs to the protein-tyrosine phosphatase family. Non-receptor class 2 subfamily.
Contains 2 SH2 domains.
Contains 1 tyrosine-protein phosphatase domain.

Phospho-SHP2 (Tyr81)抗体(antibody,
Ab)是由效应B细胞(效应**B细胞)分泌,机体用于抵御外来物质,如病毒,**等抗原,结构呈“Y”字型的球状蛋白质,仅仅存在于脊椎动物的血液和B**细胞膜表面。凡是能够跟抗体结合的物质,均被称作抗原,因此对于抗抗体(能够结合抗体的抗体)来说,抗体本身也是一种抗原物质。
Phospho-SHP2 (Tyr81)抗体普通抗体重链和轻链的结构
重链结构:普通的**球蛋白具有2条重链(H链),分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型,对应的**球蛋白名称分别为IgM、IgG、IgA、IgD和IgE。
轻链结构: 普通**球蛋白具有2条轻链(L链),分子质量约25kDa,有κ链和λ链两种亚型,这两种轻链决定了Ig的亚型类别(IgG1,IgG2,IgG3,IgG4)。一个天然的Ig分子两条轻链总是相同的,但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同,正常人血清**球蛋白κ链:λ链约为2:1,而在小鼠的比例为20:1。
2.2抗体Fab段和Fc段
IgG经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1个Fc段,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应;经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab’)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段(fragment of antigen binding,Fab),相当于抗体分子的两个臂,由一个完整的轻链和重链的VH和CH1结构域组成。Fc段为可结晶段(fragment crystallizable,Fc)相当于Ig的CH2和CH3结构域,是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区,以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2和CH3的区域,相当于Y字结构下面那一部分。
