Target Data

Function May be involved in guiding growing axons towards their targets by forming a molecular boundary that instructs axons to engage in the formation of specific nerve tracts. Binds to neuropilin. Involved in the development of the olfactory system and in neuronal control of puberty (By similarity).

  11. Overexpression of Sema3a in myocardial infarction border zone could reduce the inducibility of ventricular arrhythmias by reducing sympathetic hyper-reinnervation after infarction. PMID: 23711091
  12. Sema3A binding to CS-E in the PNNs may be a mechanism whereby PNNs restrict growth and plasticity and may represent a possible point of intervention to facilitate neuronal plasticity. PMID: 23940048
  13. In the early stages of O2-induced retinopathy, retinal microglia are activated to produce IL-1beta, which sustains the activation of microglia and induces microvascular injury through the release of Sema3A from adjacent neurons. PMID: 23766263
