Description
Imported from IPR027231

Semaphorins are a family of cell surface and soluble proteins originally identified as axon guidance factors, but are now recognised to to be involved in a wide range of functions, including neural connectivity, angiogenesis, immunoregulation, and cancer
[4, 3, 1, 5]
. Some semaphorins have an important role in the immune response, some regulate immune cell activation or differentiation, while others regulate the trafficking of immune cells
[2]
. Semaphorins signal through two major receptor families, plexins and neuropilins (Nrps). All semaphorins have a Sema domain, characterised by a seven-blade β propeller structure, which contains sites for semaphorin dimerisation and receptor binding.

Semaphorins are grouped into eight classes based on their structural domains, with classes 3-7 comprising the vertebrate semaphorins
