Hypothesis

Malin and laforin may have independent functions beyond their known interaction.

Conclusion

Malin is conserved in vertebrates and is related to TRIM32, suggesting a common evolutionary origin and functional similarities.

Supporting Evidence

  • Malin is present in all vertebrate species and a cephalochordate.
  • Malin shares significant identity with TRIM32, indicating a common evolutionary origin.
  • TRIM32 can ubiquitinate substrates that are also targeted by malin.

Takeaway

Malin is a protein that helps control how other proteins are marked for destruction in cells, and it works closely with another protein called TRIM32. They are similar but also have different jobs.

Methodology

Phylogenetic analysis and experimental validation of protein interactions and ubiquitination.

Limitations

The study does not explore the full range of potential functions for malin and TRIM32 in non-vertebrate organisms.
