Neuropilin-1 deletion constructs and their expression. A, The domain structure of full-length neuropilin-1 is shown on the left, and the deletion constructs used in this study are arrayed to the right. The domains are described in the boxed key, and the boundaries between domains are defined in Results.B, HEK293-T cells were transfected with the neuropilin-1 constructs in A. Blotted membrane preparations were probed for the myc epitope. All of the constructs generate membrane-associated recombinant proteins that are close to their expected sizes.
