Related Product Information for anti-PTPN11 antibody

SHP2, a NT2 non-receptor protein tyrosine phosphatases, contains two tandem SRC homology (SH2) domains at the N-terminus of the catalytic domain. Based on crystallographic studies, the SH2 domain is believed to function as a conformational switch which can bind and inhibit the phosphatase or bind phosphoprotein and activate the enzyme. SHP2 is thought to link growth factor receptors and other signalling proteins via protein-tyrosine phosphorylation. It may play a role in mammalian budding morphogenesis and immune response. Missense mutations in the SHP2 gene have been linked to Noonan Syndrome. Additionally, SHP2 is present in diverse neurons and is thought to play a role in abroad spectrum of neuronal responses, including neuronal survival.

NCBI Description

The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains two tandem Src homology-2 domains, which function as phospho-tyrosine binding domains and mediate the interaction of this PTP with its substrates. This PTP is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration. Mutations in this gene are a cause of Noonan syndrome as well as acute myeloid leukemia. Two transcript variants encoding different isoforms have been found for this gene.

Uniprot Description

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. Ref.17 Ref.31 Ref.32

Catalytic activity: Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. Ref.44

Subunit structure: Interacts with phosphorylated LIME1 and BCAR3. Interacts with SHB and INPP5D/SHIP1

By similarity. 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. Interacts with GAREM isoform 1 (tyrosine phosphorylated); the interaction increases MAPK/ERK activity and does not affect the GRB2/SOS complex formation. Ref.10 Ref.12 Ref.13 Ref.14 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.21 Ref.22 Ref.23 Ref.24 Ref.26 Ref.28 Ref.29 Ref.30 Ref.31 Ref.33 Ref.35 Ref.36 Ref.38

Subcellular location: Cytoplasm.

Tissue specificity: Widely expressed, with highest levels in heart, brain, and skeletal muscle. Ref.2 Ref.3 Ref.4

Domain: The SH2 domains repress phosphatase activity. Binding of these domains to phosphotyrosine-containing proteins relieves this auto-inhibition, possibly by inducing a conformational change in the enzyme.

Post-translational modification: 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. Ref.5 Ref.10 Ref.11 Ref.18 Ref.38
