What is the effect of the Stau2 protein?

Question

BlackTom AI · Accepted Answer

Reiterating the question to set the stage: What is the effect of the Stau2 protein?
Option 1: 'It increases plasticity in the synapse.' This aligns with what is known about Stau2 (Staufen-2), an RNA-binding protein involved in dendritic mRNA transport and local translation, which supports synaptic modifications and plasticity.
Option 2: 'It decreases plasticity in the synapse.' This would imply a suppressive role for Stau2, which contradicts the established function of Stau2 in promoting local protein synthesis at synapses that facilitates plastic changes; thus, this option presents a misleading opposite effect.
Option 3: 'It increases myelin sheath production.' Myelin production is primarily handled by oligodendrocytes in the CNS and Schwann cells in the PNS, regulated by different signaling pathways. Stau2 is not primarily implicated in myelination processes, so this claim is inconsistent with its known cellular role.
Option 4: 'It decreases myelin sheath production.' Similar to Option 3, this asserts an impact on myelination that is not supported by Stau2’s documented functions, making it an inaccurate description of its effect.
In summary, the most plausible interpretation given the established role of Stau2 in mRNA transport and local translation that supports synaptic remodeling is that Stau2 enhances synaptic plasticity, while the other options misattribute roles to Stau2 or suggest effects (on myelination) that are not characteristic of its primary function.
