SMN tudor domain
Also known as: SMN's globular tudor domain
Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
The SMN tudor domain is a globular protein domain from SMN that is sufficient for dimerization-induced condensation in vivo. Its condensate-forming activity requires binding to dimethylarginine, supporting its use as a chemical-input interaction module for specifying membraneless organelle assembly.
Usefulness & Problems
Why this is useful
This domain is useful as a compact protein module for coupling dimethylarginine recognition to condensate formation in living cells. The cited study further indicates that DMA-tudor interaction modules can regulate membraneless organelle assembly and define condensate composition.
Problem solved
The SMN tudor domain helps address the problem of how to encode chemically specified assembly of intracellular condensates using a defined protein interaction module. It provides a way to link dimethylarginine-dependent molecular recognition to dimerization-induced condensation in vivo.

Implementation appears to rely on the isolated SMN globular tudor domain and on dimerization-induced condensation in vivo. Practical use is expected to require access to dimethylarginine-dependent binding partners or contexts in which dimethylarginine recognition can occur, but the supplied evidence does not detail construct design beyond domain sufficiency.
The available evidence is limited to a single cited study and does not provide quantitative performance metrics, construct architectures, or cross-system benchmarking. The current evidence also does not specify host organisms, expression conditions, or the extent of validation beyond in vivo condensation assays.

The domain was reported to be sufficient for dimerization-induced condensation in vivo, indicating that the globular tudor domain alone can confer this behavior. The underlying interaction logic is supported by evidence that condensate formation requires dimethylarginine binding, and related condensate-forming behavior was observed for at least seven additional tudor domains in six proteins.
