  • Relevance
    JLP is a member of the JNK-interacting protein (JIP) group of scaffold proteins which selectively mediate JNK signaling by aggregating specific components of the MAPK cascade to form a functional JNK signaling module.
  • Cellular localization
    Cytoplasm. Cytoplasm, perinuclear region. Note: Perinuclear distribution in response to stress signals such as UV radiation.

  • Immunoprecipitation analysis of HeLa whole cell lysate (1 mg for IP, 20% of IP loaded). ab12331 was used for immunoprecipitation at 3 µg/mg lysate and used for western blot at 1 µg/ml. Lanes 1 and 2 - ab12331 IP, Lane 3 - control IgG.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) of Human seminoma using ab12331 at 1/1000 with and HRP- conjugated goat anti-rabbit secondary antibody. 

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human testis (left) and testicular seminoma (right) tissues labelling JLP with ab12331 at 1/5000 (0.2µg/ml) and 1/1000 (1µg/ml). Detection: DAB.
  • ICC/IF image of ab12331 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab12331, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
