Monoclonal Mouse Affinity Purified E IC
Semaphorin 3C (Sema3C; previously semaE) is one of six Class 3 secreted semaphorins which share 40­50% amino acid (aa) identity. Class 3 semaphorins are potent chemorepellents that function in axon and/or vascular guidance during development, and may be upregulated in tumor progression (1, 2). The 751 amino acid (aa) mouse Sema3C is highly modular. It contains a 20aa signal sequence, an ~500aa N­terminal Sema domain that forms a beta­propeller structure similar to that found in integrin molecules, a cysteine knot, a furin­type cleavage site, an Ig­like domain, and a C­terminal basic domain (1­3). Covalent dimerization plus cleavage at the C­terminus are required for activity of class 3 semaphorins (4). Mouse Sema3C shares at least 95% aa identity with human, rat, cow and dog Sema3C, and
89% and 75% aa identity with chick and zebrafish Sema3C, respectively. Type 3 semaphorins transduce signals through transmembrane plexins, either directly or by binding associated neuropilin receptors (1, 2). Sema3C signaling is transduced by Plexin­D1 indirectly via Neuropilin­1 or Neuropilin­2 receptors (5). Sema3C is expressed in all somitic motor neurons, in lung buds and in cardiac neural crest cells during development (1, 5­8). Sema3C activates integrins in certain cells so, in addition to its repulsive activities, it sometimes acts as a chemoattractant (6, 9). In the developing nervous system, this chemoattraction appears to complement Sema3A repulsion in adjacent cell layers (1, 6, 7). Sema3C also provides an attractive force opposing Sema6A and Sema6B to guide migration of neural crest endothelial cells to the cardiac outflow tract (10). Consequently, defects in aortic arch formation occur when Sema3C or Plexin­D1 genes or Sema3C­neuropilin interactions are disrupted (5, 11, 12).
