Of interest, the interaction between WDR5 and GClnc1, a long non-coding RNA (lncRNA), ensures its recruitment to a subset of pro-metastasis genes to activate transcription in gastric cancer cells[36], suggesting that non-protein factors could also contribute to the tethering of WDR5 to selective promoters although it is not clear whether these processes are independent of each other or act in concert. Here, WDR5 is linked to gastric cancer.
