Slit guidance ligand 2 (SLIT-2) is a member of the Slit family that signals through the Roundabout (Robo) receptor. It is also referred to as SLIL3. SLIT2 is expressed primarily in the fetal lung, kidney, and adult spinal cord, and to a lesser extent in adult adrenal gland, thyroid and trachea. It is initially synthesized as a 1499 amino acid precursor, which is subsequently cleaved into N-terminal and C-terminal fragments, designated as Slit2-N and Slit2-C respectively. The neurodevelopment related activities, as measured by the ability to repel olfactory bulb axons and to induce branching in dorsal root ganglia axons, are contained only in the N-terminal fragment. Recombinant human Slit2-N is a 1093 amino acid glycoprotein corresponding to the N-terminal portion of the full length Slit2 precursor. Due to glycosylation Slit2-N migrates at an apparent molecular weight of approximately 120.0-140.0kDa by SDS-PAGE analysis under reducing conditions.
Synonyms: SLIL3; Slit homolog 2 protein
Purity: >=98% (HPLC); >=98% (SDS-PAGE)
Storage: -20C
Application: Slit guidance ligand 2 (SLIT-2) has been used to treat cells in podocyte culture and in myosin II regulatory light chain (MRLC) phosphorylation assay.
Biochem Physiol Actions: Slit guidance ligand 2 (SLIT-2) acts as a repellent for axon guidance and neuronal migration, and it can also act as a chemoattractant to vascular endothelial cells and a chemotaxis inhibitor for leukocytes. It prevents the migration of T cells, neutrophils and macrophages, but enhances eosinophil migration. The protein has been shown to be downregulated in cancers.
