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 impacts nuclear organization by interacting with lamin B1 and chromosomes. This interaction can be regulated by phosphorylation during cell division. Given the nuclear localization of TMPO variants, these proteins do not seem to participate in CD90 activation.
