Background: ROBO2

Human ROBO2 is a 175 kDa member of the ROBO/roundabout receptor family and is a 1357 amino acid (aa) type I transmembrane (TM) protein. It contains an extracellular domain (ECD) comprised of five C2-type Ig-like domains and three fibronectin type III domains. ROBO receptors interact with SLIT proteins to regulate axon guidance. Similar to ROBO1, the first two Ig-like domains of ROBO2 are predicted to be important for SLIT binding. Alternate splice forms of ROBO2 exist. The ROBO2 ECD in human shares 98% aa identity with the ROBO2 ECD in mouse and canine.
