Function
Receptor for Slit proteins, at least for SLIT2, and seems to be involved in angiogenesis and vascular patterning. May mediate the inhibition of primary endothelial cell migration by Slit proteins (By similarity). Involved in the maintenance of endothelial barrier organization and function (PubMed:30455415).

Notes
While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.
Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.
The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Supportteam to know which antibody pair is suitable for this protein.

- Activity summary
Roundabout homolog 4 (Robo4) is a protein weighing approximately 107 kDa. It belongs to the immunoglobulin superfamily and is sometimes referred to as Magic Roundabout. Robo4 primarily gets expressed in endothelial cells playing an important function in vascular biology. It is characterized by having two immunoglobulin-like domains and two fibronectin type III domains making it distinct among the other Robo family members.
- Biological function summary
Robo4 stabilizes the vascular network interacting actively with the guidance molecule Slit proteins. It is not part of a larger protein complex but engages directly with these ligands to influence endothelial cell migration and vascular permeability. Its role is significant in maintaining the structural integrity of blood vessels ensuring the appropriate cellular responses important for proper vascular function.
- Pathways
Robo4 engages in the Slit-Robo signaling pathway that is essential for vascular development and remodeling. This pathway helps inhibit excessive endothelial migration and angiogenesis. Robo4 interacts with proteins like Slit2 which binds to it as a ligand to mediate these effects. Through this pathway Robo4 performs an important function in processes such as vascular homeostasis and angiogenesis regulation.
- Associated diseases and disorders
Robo4 appears to have connections to vascular-related conditions including diabetic retinopathy and age-related macular degeneration. The protein influences pathological angiogenesis which is a hallmark in the progression of these diseases. In these contexts Robo4's interaction with Slit2 proves important as it can restrain abnormal vascular growth offering potential therapeutic angles for treatment approaches focused on targeting the Slit-Robo pathway.
