  • Target

    • Pathway
      Amino-acid biosynthesis; L-arginine biosynthesis; L-arginine from L-ornithine and carbamoyl phosphate: step 2/3.
      Nitrogen metabolism; urea cycle; (N(omega)-L-arginino)succinate from L-aspartate and L-citrulline: step 1/1.
    • Involvement in disease
      Defects in ASS1 are the cause of citrullinemia type 1 (CTLN1) [MIM:215700]. Citrullinemia belongs to the urea cycle disorders. It is an autosomal recessive disease characterized primarily by elevated serum and urine citrulline levels. Ammonia intoxication is another manifestation. CTLN1 usually manifests in the first few days of life. Affected infants appear normal at birth, but as ammonia builds up in the body they present symptoms such as lethargy, poor feeding, vomiting, seizures and loss of consciousness. Less commonly, a milder CTLN1 form can develop later in childhood or adulthood.
    • Sequence similarities
      Belongs to the argininosuccinate synthase family. Type 1 subfamily.

    • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: ASS1 knockout HAP1 whole cell lysate (20 µg)
      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 - ab170900 observed at 47 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab170900 was shown to recognize ASS1 when ASS1 knockout samples were used, along with additional cross-reactive bands. Wild-type and ASS1 knockout samples were subjected to SDS-PAGE. ab170900 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 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 1/10000 dilution for 1 hour at room temperature before imaging.

    • Western blot analysis on immunoprecipitation pellet from (1) HeLa cell lysate or (2) 1X PBS (negative control) using ab170900 at a 1/10 dilution, and HRP-conjugated anti-rabbit IgG preferentially detecting the non-reduced form of rabbit IgG.
