Neuropilins have recently been characterized as receptors for
secreted semaphorins. Here, we report the generation of a dominant negative form of neuropilin-1 by the deletion of one of its
extracellular domains. Expression of this variant in cultured primary
sympathetic neurons blocks the paralysis of growth cone motility
normally induced by SEMA-3A (collapsin-1, semaphorin III, semaphorin D) and SEMA-3C (collapsin-3, semaphorin E) but not that induced by SEMA-3F
(semaphorin IV). A truncated form of neuropilin-1 that is missing its
cytoplasmic domain fails to act as a dominant negative receptor
component. These results suggest that neuropilin-1 is a necessary
component of receptor complexes for some, but not all, secreted
semaphorin family members. Overexpression of dominant negative
neuropilins should provide a powerful new method of blocking the
functions of secreted semaphorins.
