Target

  • Function

    Phosphorylates PtdIns, PtdIns4P and PtdIns(4,5)P2 with a preference for PtdIns(4,5)P2.
  • Involvement in disease

    Defects in PIK3CA are associated with colorectal cancer (CRC) [MIM:114500].
    Defects in PIK3CA are a cause of susceptibility to breast cancer (BC) [MIM:114480]. A common malignancy originating from breast epithelial tissue. Breast neoplasms can be distinguished by their histologic pattern. Invasive ductal carcinoma is by far the most common type. Breast cancer is etiologically and genetically heterogeneous. Important genetic factors have been indicated by familial occurrence and bilateral involvement. Mutations at more than one locus can be involved in different families or even in the same case.
    Defects in PIK3CA are a cause of susceptibility to ovarian cancer (OC) [MIM:167000]. Ovarian cancer common malignancy originating from ovarian tissue. Although many histologic types of ovarian neoplasms have been described, epithelial ovarian carcinoma is the most common form. Ovarian cancers are often asymptomatic and the recognized signs and symptoms, even of late-stage disease, are vague. Consequently, most patients are diagnosed with advanced disease.
    Defects in PIK3CA may underlie hepatocellular carcinoma (HCC) [MIM:114550].
    Defects in PIK3CA are a cause of keratosis seborrheic (KERSEB) [MIM:182000]. A common benign skin tumor. Seborrheic keratoses usually begin with the appearance of one or more sharply defined, light brown, flat macules. The lesions may be sparse or numerous. As they initially grow, they develop a velvety to finely verrucous surface, followed by an uneven warty surface with multiple plugged follicles and a dull or lackluster appearance.
  • Sequence similarities

    Belongs to the PI3/PI4-kinase family.
    Contains 1 C2 domain.
    Contains 1 PI3K/PI4K domain.

    Lane 3: HeLa whole cell lysate (20 µg)
    Lane 4: Jurkat whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab183957 observed at 125 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab183957 was shown to recognize PI 3 Kinase catalytic subunit alpha/PIK3CA in wild type cells as signal was lost at the expected MW in PI 3 Kinase catalytic subunit alpha/PIK3CA knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and PI 3 Kinase catalytic subunit alpha/PIK3CA knockout samples were subjected to SDS-PAGE. ab183957 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    Immunoprecipitation - Anti-PI 3 Kinase catalytic subunit alpha/PIK3CA antibody [EPR19693] (ab183957)

    PI 3 Kinase catalytic subunit alpha/PIK3CA was immunoprecipitated from 0.35 mg of mouse hypothalamus lysate with ab183957 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab183957 at 1/500 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution.

    Lane 1: Mouse hypothalamus lysate, 10µg (Input).
    Lane 2: ab183957 IP in mouse hypothalamus lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 3 minutes.
