ターゲット情報

  • 機能

    Acts downstream of various receptor and cytoplasmic protein tyrosine kinases to participate in the signal transduction from the cell surface to the nucleus.

    Defects in PTPN11 are the cause of LEOPARD syndrome type 1 (LEOPARD1) [MIM:151100]. It is an autosomal dominant disorder allelic with Noonan syndrome. The acronym LEOPARD stands for lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormalities of genitalia, retardation of growth, and deafness.
    Defects in PTPN11 are the cause of Noonan syndrome type 1 (NS1) [MIM:163950]. Noonan syndrome (NS) is a disorder characterized by dysmorphic facial features, short stature, hypertelorism, cardiac anomalies, deafness, motor delay, and a bleeding diathesis. Some patients with Noonan syndrome type 1 develop multiple giant cell lesions of the jaw or other bony or soft tissues, which are classified as pigmented villomoduolar synovitis (PVNS) when occurring in the jaw or joints. Note=Mutations in PTPN11 account for more than 50% of the cases. Rarely, NS is associated with juvenile myelomonocytic leukemia (JMML). NS1 inheritance is autosomal dominant.
    Defects in PTPN11 are a cause of juvenile myelomonocytic leukemia (JMML) [MIM:607785]. JMML is a pediatric myelodysplastic syndrome that constitutes approximately 30% of childhood cases of myelodysplastic syndrome (MDS) and 2% of leukemia. It is characterized by leukocytosis with tissue infiltration and in vitro hypersensitivity of myeloid progenitors to granulocyte-macrophage colony stimulating factor.
    Defects in PTPN11 are a cause of metachondromatosis (MC) [MIM:156250]. It is a skeletal disorder with radiologic fetarures of both multiple exostoses and Ollier disease, characterized by the presence of multiple enchondromas and osteochondroma-like lesions.

  • 配列類似性

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

  • ドメイン

    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.

  • 翻訳後修飾

    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.

    Immunofluorescence analysis of SHP2 (phosho S576) was done on 70% confluent log phase NIH/3T3 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with SHP2 (phosho S576) Rabbit Polyclonal Antibody (ab17940) at 1/250 dilution in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate at a dilution of 1/2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI. F-actin (Panel c: red) was stained with Rhodamine Phalloidin (1/300). Panel d is a merged image showing nuclear localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Question

Looking through both protocols, it seems that this enquiry and the other (CCEID:743720 - ab13948) are from the same customer. Is that correct? Ye, same customer. - First of all, I would like to clarify that ab17940 is not SOCS4 but SHP2 (phospho S576) - you say in your e-mail Rabbit Polyclonal to SOCS4(abcam)). --> Our customer had confused. Your are all right. - I would highly recommend using RIPA buffer and not TCA for precipitation. This buffer contains a cocktail of different proteinase inhibitors which help prevent the degradation of the target protein. TCA may destroy the epitipe(s) and can cause some detection problem. Actually, we have not used TCA protein precipitates for testing and characterizing this product (and any of our other antibodies), therefore we have no experience with this type of extraction. ---> She changed buffer with RIPA, but the results were same. - You have written in your e-mail: Incubation for 2h at room temp. or overnight at 4? Question: Could you please specify if it was a 2hr or overnight incubation? It is not clear from your message. She had tried to incubation both of them, and she had same results. - Since the antibody recognizes the phosphorylated SH2 protein, it is important to use 5% BSA as blocking agent rather than milk.Milk may cause high background staining. I would also suggest that the customer should use positive control i.e. Hek293 cells treated with PMA. She had used 5% BSA but no differece with milk. - Does the sample express high levels of phosphorylated SHP2? She do not have reference, but she had complaint with background. - Please also advise your customer to load at least 20-30 ug protein per lane. She had loaded 30ug per lane, but obtained same results. - Is the secondary antibody works properly? Has the customer used it successfully with another primary antibody? It would be advisable to run a no primary – only secondary antibody – control to see if the high background signal is still there. She had a good results using other primary antibody.

Answer

Dr Bagrij is away from the office for a few days and I will do my best to help you to prevent delays for you and the customer. I understand that the customer has experienced problems with ab17940 and ab13948. You also sent to me today a complaint for ab3695 with a protocol very similar to the other protocols, is this the same customer? If so this makes me think there is a problem with the storage of the antibodies, the samples, or something gone off in the buffers used in all experiments or the preservation condition of the lysates has not been adequate. We have not received any other complaints about those antibodies. Can you please clarify if the customer is seeing the correct band plus high background or just high background? As Dr Bagrij mentioned it is possible that the customer's samples do not contain the phosphorylated form of SHP2 protein or the SOCS4 protein or that total SHP2 is not even in the samples. I would recommend to run the positive control of Hek293 cells treated with PMA (which induces the phosphorylation) and to make sure the protease inhibitors in the lysis buffer are fresh and of high concentration. What buffer and protease inhibitors were used? I was able to find the lysis buffer used with the HEK293 treated cell lysate, as you can see Triton or NP40 is essential to lyse the cells properly: 10 mM Tris, pH 7.4 100 mM NaCl 1 mM EDTA 1 mM EGTA 1 mM NaF 20 mM Na4P2O7 2 mM Na3VO4 0.1% SDS 0.5% sodium deoxycholate 1% Triton-X 100 10% glycerol 1 mM PMSF (made from a 0.3 M stock in DMSO) or 1 mM AEBSF (water soluble version of PMSF) 60 µg/mL aprotinin 10 µg/mL leupeptin 1 µg/mL pepstatin (alternatively, protease inhibitor cocktail such as Sigma Cat. # P2714 may be used). For ab13948 I am trying to find out the recommended positive control to help the customer. I would appreciate if you can provide the images of the blots before Dr Bagrij's recommendations and after, to help me diagnose the problem better. It is still very difficult at this stage to see what the problem might be and this will help me a lot. I appreciate your help with this matter and look forward to hearing from you,
