  • Function

    Receptor for SLIT1 and SLIT2 which are thought to act as molecular guidance cue in cellular migration, including axonal navigation at the ventral midline of the neural tube and projection of axons to different regions during neuronal development. In axon growth cones, the silencing of the attractive effect of NTN1 by SLIT2 may require the formation of a ROBO1-DCC complex. May be required for lung development.
  • Tissue specificity

    Widely expressed, with exception of kidney.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily. ROBO family.
    Contains 3 fibronectin type-III domains.
    Contains 5 Ig-like C2-type (immunoglobulin-like) domains.
  • Post-translational

    Ubiquitinated. May be deubiquitinated by USP33.

  • All lanes : Anti-Robo1 antibody (ab85312) at 1 µg/ml

    Lane 1 : Human brain tissue lysate - total protein (ab29466)
    Lane 2 : Brain (Mouse) Tissue Lysate

    Lysates/proteins at 10 µg per lane.

    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: 180 kDa
    Observed band size: 190 kDa
    why is the actual band size different from the predicted?

    Exposure time: 20 minutes

    Human Roundabout homolog 1 precursor contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
  • ICC/IF image of ab85312 stained HeLa cells. The cells were 4% PFA 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 (ab85312, 5µg/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.
