Plexin-B1 mutations in prostate cancer.
Semaphorins are a large class of secreted or membrane-associated proteins that act as chemotactic cues for cell movement via their transmembrane receptors, plexins. We hypothesized that the function of the semaphorin signaling pathway in the control of cell migration could be harnessed by cancer cells during invasion and metastasis. We now report 13 somatic missense mutations in the cytoplasmic...
متن کاملAnalysis of the interaction of Plexin-B1 and Plexin-B2 with Rnd family proteins
The Rnd family of proteins, Rnd1, Rnd2 and Rnd3, are atypical Rho family GTPases, which bind to but do not hydrolyse GTP. They interact with plexins, which are receptors for semaphorins, and are hypothesised to regulate plexin signalling. We recently showed that each Rnd protein has a distinct profile of interaction with three plexins, Plexin-B1, Plexin-B2 and Plexin-B3, in mammalian cells, alt...
متن کاملSema4D induces angiogenesis through Met recruitment by Plexin B1.
Semaphorins, a large family of membrane-bound and secreted proteins, signal through their transmembrane receptors, the plexins. Semaphorins and plexins share structural homologies with scatter factor receptors, a family of tyrosine kinase receptors for which Met is the prototype. Semaphorins have been studied primarily in the developing nervous system, where they act as repelling cues in axon g...
متن کاملPlexin-B2, but not Plexin-B1, critically modulates neuronal migration and patterning of the developing nervous system in vivo.
Semaphorins and their receptors, plexins, have emerged as important cellular cues regulating key developmental processes. B-type plexins directly regulate the actin cytoskeleton in a variety of cell types. Recently, B-type plexins have been shown to be expressed in striking patterns in the nervous system over critical developmental windows. However, in contrast to the well characterized plexin-...
متن کاملSoluble CD100 functions on human monocytes and immature dendritic cells require plexin C1 and plexin B1, respectively.
CD100 represents the first semaphorin described in the immune system. It is expressed as a 300-kDa homodimer at the surface of most hematopoietic cells, but is also found in a soluble form following a proteolytic cleavage upon cell activation. We herein established that soluble CD100 (sCD100) impaired the migration of human monocytes and immature dendritic cells (DCs), but not of mature DCs. Pe...
