To gain insight into the functional significance of the interaction between Nrp1 and FlnA, we tracked their localization in VEGF-A-treated nrp1+/+ ECs. Whereas there was little or no colocalization in quiescent ECs (Fig. 3A), the two proteins colocalized extensively in vesicular punctae in the cytoplasm 5 min after the introduction of VEGF-A (Fig. 3B). The extent of colocalization decreased at the later time points of 10 and 30 min (Fig. 3C-E). To test for the dependence of the colocalization of Nrp1 and FlnA on the cytoplasmic interaction of the two proteins, we probed their localization in nrp1cyto ECs. The Nrp1 population did not undergo noticeable redistribution after the application of VEGF-A, and it did not colocalize with FlnA (Fig. 3A, B). Rather, Nrp1 remained concentrated along the cell edges, as in quiescent nrp1cyto cells. horowia@ccf.org FEBS Lett.

proteomics approach to identify cytoplasmic proteins that associate with Nrp1. Immunoprecipitates of Nrp1 from quiescent and from VEGF-A164-treated (20 ng/ml, 5 min) primary mouse heart ECs were resolved by SDS-PAGE. The band patterns of the two samples were partially different (Fig. 1, Table 1). The proteins were identified by liquid chromatographytandem mass spectroscopy (LC-MS). In the quiescent ECs, these proteins were cytoplasmic dynein heavy chain 1 (Dync1h1), myosin heavy chains 9 and 10 (Mhy9, Mhy10), and eukaryotic translation elongation factor 1 α1 (EEF1α1). Mhy9, Mhy10, and EEF1α1 were present in the immunoprecipitate from both VEGF-treated and quiescent ECs. Mhy9 and Myh10 are subunits of non-muscle myosin II, known also as heavy chains IIa and IIb. They are involved in endosomal trafficking [24], cytokinesis [25], and cell shape remodeling [26], and are localized to early endosomes, stress-fibers, and FAs [27]. The proteins unique to the VEGF-treated sample were α-enolase and Filamin-A (FlnA). nrp1-dync1h1 1435703 n/a EEF1alpha1 1435711 unspecified role unspecified role prey prey living cell living cell n/a Myh9 1435712 unspecified role unspecified role prey prey living cell living cell n/a Dync1h1 1435715 unspecified role unspecified role prey prey living cell living cell n/a Myh10 1435713 unspecified role unspecified role prey prey living cell living cell n/a NRP1 1435707 unspecified role unspecified role bait bait living cell living cell association association false false false t1 f1 We used a proteomics approach to identify cytoplasmic proteins that associate with Nrp1.
