LAP2 plays a role in the regulation of nuclear architecture by binding lamin B1 and chromosomes. This interaction is regulated by phosphorylation during mitosis. Given the nuclear localization of the three TMPO isoforms, it is unlikely that these proteins play any role in CD90 induction.
LAP2 influences nuclear architecture through its binding to lamin B1 and chromosomes. Phosphorylation affects this interaction during mitosis. Since all three TMPO isoforms are found in the nucleus, it is unlikely that they contribute to CD90 induction.
