ID:SLIT2_HUMAN DESCRIPTION: RecName: Full=Slit homolog 2 protein; Short=Slit-2; Contains: RecName: Full=Slit homolog 2 protein N-product; Contains: RecName: Full=Slit homolog 2 protein C-product; Flags: Precursor; FUNCTION: Thought to act as molecular guidance cue in cellular migration, and function appears to be mediated by interaction with roundabout homolog receptors. During neural development involved in axonal navigation at the ventral midline of the neural tube and projection of axons to different regions. SLIT1 and SLIT2 seem to be essential for midline guidance in the forebrain by acting as repulsive signal preventing inappropriate midline crossing by axons projecting from the olfactory bulb. In spinal chord development may play a role in guiding commissural axons once they reached the floor plate by modulating the response to netrin. In vitro, silences the attractive effect of NTN1 but not its growth- stimulatory effect and silencing requires the formation of a ROBO1-DCC complex. May be implicated in spinal chord midline post- crossing axon repulsion. In vitro, only commissural axons that crossed the midline responded to SLIT2. In the developing visual system appears to function as repellent for retinal ganglion axons by providing a repulsion that directs these axons along their appropriate paths prior to, and after passage through, the optic chiasm. In vitro, collapses and repels retinal ganglion cell growth cones. Seems to play a role in branching and arborization of CNS sensory axons, and in neuronal cell migration. In vitro, Slit homolog 2 protein N-product, but not Slit homolog 2 protein C-product, repels olfactory bulb (OB) but not dorsal root ganglia (DRG) axons, induces OB growth cones collapse and induces branching of DRG axons. Seems to be involved in regulating leukocyte migration. SUBUNIT: Interacts with GREM1 (By similarity). Homodimer. Binds ROBO1 and ROBO2 with high affinity. SUBCELLULAR LOCATION: Secreted. Note=The C-terminal cleavage protein is more diffusible than the larger N-terminal protein that is more tightly cell associated. TISSUE SPECIFICITY: Fetal lung and kidney, and adult spinal cord. Weak expression in adult adrenal gland, thyroid, trachea and other tissues examined. DOMAIN: The leucine-rich repeat domain is sufficient for guiding both axon projection and neuronal migration, in vitro. SIMILARITY: Contains 1 CTCK (C-terminal cystine knot-like) domain. SIMILARITY: Contains 7 EGF-like domains. SIMILARITY: Contains 1 laminin G-like domain. SIMILARITY: Contains 20 LRR (leucine-rich) repeats. SIMILARITY: Contains 4 LRRCT domains. SIMILARITY: Contains 4 LRRNT domains.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
