'''Semaphorin''' (SEMA) are membrane proteins which act as axonal growth guidance molecules. SEMA act as short-range inhibitory signal. There are 8 classes of SEMA numbered 1 to 7 and V (viral). Each class has several subgroups which share similar characteristics. | '''Semaphorin''' (SEMA) are membrane proteins which act as axonal growth guidance molecules.
