Input: P-glycoprotein upregulates these complexes to facilitate the proliferation of dendritic cells, and one of their protein constituents has been found to associate with and regulate multiple growth- and transcription-related proteins, such as PTEN and c-Jun. One protein that makes up these complexes also catalyzes telomere addition to the ends of chromosomes and is called TEP1. They can be mobilized along microtubules to associate with the nuclear envelope, giving credence to the theory that they may be involved in intracellular transport processes. Ninety-six copies of their major protein constituent self-assemble into a barrel-like structure, although these organelles can also open into an octahedral flower-like configuration. These organelles' internal RNA molecules bind argonaute proteins and may mediate drug resistance in cancer cells. For 10 points, name these highly conserved cytoplasmic ribonucleoprotein organelles of 39-fold symmetry and uncertain function.
