  • Function

    Binds cAMP regulatory element DNA sequence. May play a role in RNA splicing.
  • Tissue specificity

    Widely expressed. Highest levels in heart, brain, pancreas, thymus, ovary, small intestine and peripheral blood leukocytes, as well as cerebellum, putamen and pituitary gland. Lowest levels in lung, liver and kidney. Also expressed in fetal tissues, including brain, heart, kidney, thymus and lung.
  • Sequence similarities

    Belongs to the Luc7 family.
  • Post-translational

    Phosphorylated in vitro by SRPK1, SRPK2 and CLK1.
  • Cellular localization

    Nucleus speckle. The subnuclear localization is affected by cisplatin.

    All lanes : Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 51 kDa
    Observed band size: 60 kDa
    why is the actual band size different from the predicted?

    The 60 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to CROP.
  • ICC/IF image of ab79231 stained MCF7 cells. The cells were 100% methanol fixed (5 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 (ab79231, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 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.
