Application Abreviews Notes
WB 1/500 - 1/1000. Detects a band of approximately 21 kDa.
IP 1/50 - 1/60.
  • Application notes
    Is unsuitable for IHC.
  • Target

    • Function
      Ras proteins bind GDP/GTP and possess intrinsic GTPase activity.
    • Involvement in disease
      Defects in HRAS are the cause of faciocutaneoskeletal syndrome (FCSS) [MIM:218040]. A rare condition characterized by prenatally increased growth, postnatal growth deficiency, mental retardation, distinctive facial appearance, cardiovascular abnormalities (typically pulmonic stenosis, hypertrophic cardiomyopathy and/or atrial tachycardia), tumor predisposition, skin and musculoskeletal abnormalities.
      Defects in HRAS are the cause of congenital myopathy with excess of muscle spindles (CMEMS) [MIM:218040]. CMEMS is a variant of Costello syndrome.
      Defects in HRAS may be a cause of susceptibility to Hurthle cell thyroid carcinoma (HCTC) [MIM:607464]. Hurthle cell thyroid carcinoma accounts for approximately 3% of all thyroid cancers. Although they are classified as variants of follicular neoplasms, they are more often multifocal and somewhat more aggressive and are less likely to take up iodine than are other follicular neoplasms.
      Note=Mutations which change positions 12, 13 or 61 activate the potential of HRAS to transform cultured cells and are implicated in a variety of human tumors.
      Defects in HRAS are a cause of susceptibility to bladder cancer (BLC) [MIM:109800]. A malignancy originating in tissues of the urinary bladder. It often presents with multiple tumors appearing at different times and at different sites in the bladder. Most bladder cancers are transitional cell carcinomas. They begin in cells that normally make up the inner lining of the bladder. Other types of bladder cancer include squamous cell carcinoma (cancer that begins in thin, flat cells) and adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids). Bladder cancer is a complex disorder with both genetic and environmental influences.
      Note=Defects in HRAS are the cause of oral squamous cell carcinoma (OSCC).
    • Sequence similarities
      Belongs to the small GTPase superfamily. Ras family.
    • Post-translational
      Palmitoylated by the ZDHHC9-GOLGA7 complex. A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi.
      S-nitrosylated; critical for redox regulation. Important for stimulating guanine nucleotide exchange. No structural perturbation on nitrosylation.
    • Cellular localization
      Cell membrane. Golgi apparatus membrane. The active GTP-bound form is localized most strongly to membranes than the inactive GDP-bound form (By similarity). Shuttles between the plasma membrane and the Golgi apparatus.

    ab97488 and ab6548 are alternative to sc-520. Please note this assumption is based on the location of immunogen only. We might not have similar species or application data.
    ab140962 and ab140377 are expected alternatives for sc29.
    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Thank you for contacting us with your enquiry.
    I have run some alignments between the immunogens of ab64705 and ab96548, and ab96548 is more specific for HRas. The immunogen of ab64705 overlaps quite a bit with N and KRas, however ab96548 shows no significant similarity to KRas and very little (47%) to NRas.
    We only have the full size vials of all of our products and are not able to send trial sizes. However, as ab96548 has not been tested in murine samples, you are eligible for our testing discount program if you would like to try this antibody in mouse. For this program, you would initially purchase ab96548, test it in mouse, then submit an Abreview with your data. In exchange we will give you a discount code valid for one free primary antibody on a future order.
    I hope this information will be useful. Please let me know if you have any questions, or if you would like to participate in our testing discount program, and I will be happy to arrange that for you.
