  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Required for normal viability, growth and fertility.
    • Pathway

      Amine and polyamine biosynthesis; spermine biosynthesis; spermine from spermidine: step 1/1.
    • Involvement in disease

      Defects in SMS are the cause of Snyder-Robinson syndrome (SRS) [MIM:309583]; also known as X-linked mental retardation Snyder-Robinson type. SRS is characterized by moderate intellectual deficit, hypotonia, an unsteady gait, osteoporosis, kyphoscoliosis and facial asymmetry. Transmission is X-linked recessive.
    • Sequence similarities

      Belongs to the spermidine/spermine synthase family.
    • Domain

      Composed of 3 domains: the N-terminal domain has structural similarity to S-adenosylmethionine decarboxylase, the central domain is made up of four beta strands and the C-terminal domain is similar in structure to spermidine synthase. The N- and C-terminal domains are both required for activity.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: Spermine synthase knockout HAP1 cell lysate (20 µg)
      Lane 3: HeLa cell lysate (20 µg)
      Lanes 1 - 3: Merged signal (red and green). Green - ab156879 observed at 40 kDa. Red - loading control, ab18058, observed at 124 kDa.
      ab156879 was shown to specifically react with Spermine synthase when Spermine synthase knockout samples were used. Wild-type and Spermine synthase knockout samples were subjected to SDS-PAGE. ab156879 and ab18058 (loading control to vinculin) were diluted 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
