XPO1 and non-Hodgkin lymphoma: While the additional RNA cargos were not identified as XPO1 targets in lymphoma, they bear mentioning here as potentially important cargo in NHL despite the lack of definitive, supporting evidence Ribosomal RNA (rRNA), small nuclear RNA (snRNA), and micro RNA (miRNA) are exported into the cytoplasm by XPO1 with the help of adaptor proteins such as NMD3, the cap binding protein CBC, and the phosphorylated adaptor for RNA export (PHAX) [31].
