NRH1 and Wnt signaling come together in convergent extension
...phins are molecules that function in the survival, growth
and migration of neurons.) However, on testing its affinity for neurotrophin ligands, the group found that, unlike p75NTR, NRH1 did not bind with neurotrophins, which led them to seek other biological roles for the protein. Experiments in which NRH1 ...
