Cytoskeleton Transcriptional Regulation via ACTive Transport

Molecules called kinesins are critical for the movement of chromosomes, organelles, and messenger RNAs molecules within cells. Macho et al. now show that the testis-specific kinesin KIF17b can function in the transport of the coactivator ACT and affect transcriptional activity. ACT is a coactivator of CREM-mediated transcription in mammalian spermatids. KIF17b acts as a dose-dependent inhibitor of ACT-dependent transcription by excluding ACT from the nucleus. This work begins to address the molecular mechanism by which germ-cell gene expression is regulated.
