			R-HSA-8854466 (Reactome)	Reelin (RELN) (DeSilva et al. 1997) is an extracellular matrix serine protease highly expressed in the brain that plays a role in neural cell positioning during brain development by regulating their microtubule function and neuronal migration. It can bind to the extracellular domains of lipoprotein receptors VLDLR and APOER2 to induce tyrosine phosphorylation of disabled-1 (DAB1), an adaptor protein bound to the cytoplasmic tails of these receptors that is a phosphorylation target for a signaling cascade trigggered by RELN. This suggests VLDLR and APOER2 participate in transmitting the extracellular RELN signal to intracellular signaling processes initiated by DAB1 (Hiesberger et al. 1999). In post-mortem studies of schizophrenia sufferers, RELN was found to be significantly reduced (by up to 50%) in brain samples whereas DAB1 was observed to be at normal levels, suggesting a role for RELN in schizophrenia (Impagnatiello et al. 1998).
			R-HSA-8855232 (Reactome)	Reelin (RELN) is an extracellular matrix serine protease highly expressed in the brain that plays a role in neural cell positioning during brain development by regulating their microtubule function and neuronal migration. It can bind to the extracellular domains of lipoprotein receptors VLDLR and APOER2 to induce tyrosine phosphorylation of disabled-1 (DAB1), an adaptor protein bound to the cytoplasmic tails of these receptors that is a phosphorylation target for a signaling cascade trigggered by RELN (Bar et al. 2003, for a review see Gao & Godbout 2013).
			R-HSA-8855237 (Reactome)	One of the three domains in disabled homolog 1 (DAB1) is a tyrosine-rich region consists of five highly conserved tyrosine residues; Y185, Y198, Y200, Y220 and Y232. These residues correspond to two consensus Src family kinase recognition sites (YQxI, Y185 and Y198) and two consensus Abl/Crk recognition sites (YxVP, Y220 and Y232). At least three of the tyrosine residues (Y198, Y220 and Y232) can be phosphorylated by the Src kinase family member, tyrosine protein kinase fyn (FYN) in response to Reelin (RELN) stimulation (Katyal et al. 2007). Tyrosine-phosphorylated DAB1 acts as a hub to recruit different Src homology 2 (SH2) domain-containing proteins, including the p85 regulatory subunit of phosphatidylinositide-3-kinase (PI3K), cellular adaptors CrkL, Crk, Nck-beta and SOCS (suppressor of cytokine signaling) (Gao & Godbout 2013). Tyrosine phosphorylation of DAB1 also appears to strengthen the association of DAB1 with SH3KBP1 (aka CIN85), an adaptor protein involved in endocytic down-regulation of receptor-tyrosine kinases (Fuchigami et al. 2013).
			R-HSA-8855259 (Reactome)	SH3 domain-containing kinase-binding protein 1 (SH3KBP1, aka CIN85) is an adapter protein involved in the regulation of endocytosis and lysosomal degradation of ligand-induced receptor tyrosine kinases (Fuchigami et al. 2013).
