Lafora disease (LD), an autosomal recessive and fatal form of neurodegenerative disorder, is characterized by the presence of polyglucosan inclusions in the affected tissues including the brain. LD can be caused by defects either in the 𝐸𝑃𝑀2𝐴 gene coding for the laforin protein phosphatase or the 𝑁𝐻𝐿𝑅𝐶𝐼 gene coding for the malin ubiquitin ligase. Since the clinical symptoms of LD patients representing the two genetic groups are very similar and since malin is known to interact with laforin, we were curious to examine the possibility that the two proteins regulate each others function. Using cell biological assays we demonstrate here that
malin promotes its own degradation via auto-ubiquitination,
laforin prevents the auto-degradation of malin by presenting itself as a substrate and
malin preferentially degrades the phosphatase-inactive laforin monomer. Our results that laforin and malin regulate each others stability and activity offers a novel and attractive model to explain the molecular basis of locus heterogeneityobserved in LD.

To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".
Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.
Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.
Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
