disease:Defects in ROBO1 may be a cause of breast and lung cancer. ROBO1 maps within a region of overlapping homozygous deletions characterized in both small cell lung cancer cell lines (SCLC) and in a breast cancer cell line.,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.,similarity:Belongs to the immunoglobulin superfamily. ROBO family.,similarity:Contains 3 fibronectin type-III domains.,similarity:Contains 5 Ig-like C2-type (immunoglobulin-like) domains.,subunit:Interacts with SLIT1 and SLIT2.,tissue specificity:Widely expressed, with exception of kidney.,
Cell membrane ; Single-pass type I membrane protein . Cell projection, axon . Endoplasmic reticulum-Golgi intermediate compartment membrane ; Single-pass membrane protein . Detected at growth cones in thalamus neurons. Detected at growth cones in thalamus neurons (By similarity). PRRG4 prevents cell surface location and both colocalize in the Endoplasmic reticulum/Golgi adjacent to the cell nucleus (By similarity). .
Widely expressed, with exception of kidney.
