- semaphorin 1 《英文msh词典》Semaphorin 1 ; [入口词] Semaphorin 1 ; [主题词] Semaphorins ; [英文释义] A family of proteins that mediate axonal guidance. Semaphorins act as repulsive cues for neuronal GROWTH CONES and bind to receptors on their filopodia. At least 20 different molecules have been described and divided into eight classes based on domain organization and species of origin. Classes 1 and 2 are invertebrate,classes 3-7 are vertebrate,and class V are viral. Semaphorins may be secreted (classes 2,3,and V),transmembrane (classes 1,4,5,and 6),or membrane-anchored (class 7). All semaphorins possess a common 500-amino acid extracellular domain which is critical for receptor binding and specificity,and is also found in plexins and scatter factor receptors. Their C termini are class-specific and may contain additional sequence motifs.

- semaphorin 3a 《英文msh词典》Semaphorin 3A ; [入口词] Semaphorin 3A ; [主题词] Semaphorin-3A ; [英文释义] The prototypical and most well-studied member of the semaphorin family. Semaphorin-3A is an axon-repulsive guidance cue for migrating neurons in the developing nervous system. It has so far been found only in vertebrates,and binds to NEUROPILIN-1/plexin complex receptors on growth cones. Like other class 3 semaphorins,it is a secreted protein.
