FIGURE 3.
NRXN interacts with exocytotic and docking proteins in the INS-1E β-cell line. Anti-NRXN1 immunoprecipitates from INS-1E cells were immunoblotted for the indicated proteins (NRXN1 IP, lane 3) using isotype-matched control IgG immunoprecipitates as controls (Control IP, lane 2). Total lysate is represented in lane 1. The experiments were repeated with similar results.
