Annotation description:The adhesive interactions of the synaptic adhesion molecule SynCAM 1 were mapped in this study.
The homophilic binding of SynCAM 1 extracellular domains in trans is shown in Fig. 5, using a bead aggregation assay and a cell-cell contact analysis.
Testing heterophilic interactions, the affinity chromatography results in Fig. 6A show that heterologously expressed SynCAM 1 retains not only SynCAM 1 but also SynCAM 2 from adult rat forebrain extracts. Beads coated with SynCAMs 2 and 3 each retain SynCAM 1 from forebrain extracts. Heterophilic interactions of SynCAM 1 and SynCAM 2 are further supported by the analysis of cell-cell contact assembly in Fig. 6B. All interactions are Ca2+ independent.

Additional literature:Using a cell aggregation assay, the data in Fig.1 demonstrate the homophilic interaction of SynCAM1/nectin-like molecule 2. This is supported by a cell-cell contact analysis in Fig. 6. The heterophilic interaction of SynCAM 1 and SynCAM3/nectin-like molecule 1 is shown in Fig. 2. @ PMID:12826663

Using a cell overlay assay, Fig. 1 shows the heterophilic interaction of SynCAM 1 with SynCAM 2 and the heterophilic interactions of both SynCAM 2 and SynCAM 3 with SynCAM 1. @ PMID:18615557

The experiments shown in Fig. 4 use a cell overlay approach to show the homophilic interaction of SynCAM1/nectin-like molecule 2 and the heterophilic interaction of SynCAM 1 with SynCAM 3/nectin-like molecule 1. @ PMID:17724124

The homophilic binding of SynCAM 1 via its extracellular immunoglobulin domains is shown in Fig. 2B using a cell aggregation assay. @ PMID:12202822
