Microtubule polarity helps govern important processes in neurons to ensure that the neurons are functioning properly. From our group’s research it is understood that Goα localizes in dendrite branchpoints and may play a crucial role in wnt signaling. It is also hypothesized that the ligand that causes gammatubulin to localize at dendrite branchpoints comes from the skin cells. At the ends of neurons, we see that proteins associated with microtubule nucleation are present.
