Jan Larsson

Jan Larsson is a Professor at the Department of Molecular Biology, Umeå University, Sweden. His research focuses on chromosome-specific gene regulation and genomic organization in *Drosophila melanogaster*.

• Active researcher with a dedicated lab studying chromatin dynamics and epigenetic mechanisms.
• Key projects include analysis of the Painting of Fourth (POF) protein and histone modifications.

His work explores how chromosomes maintain functional integrity and coordinate gene expression, particularly in contexts of aneuploidy and dosage compensation. Current projects funded by the Swedish Cancer Society investigate chromosomal regulatory systems and their evolutionary adaptations.

Scientific contributions span chromosome-wide regulatory mechanisms, with recent studies on H3K36 methylation, transposon control, and RNA stability in gene expression buffering. Collaborative publications highlight interactions between non-coding RNAs and chromatin proteins like HP1a and MSL complex.
