LARP1 functions as a molecular switch for mTORC1-mediated translation of an essential class of mRNAs (Hong et al., 2017) and posttranscriptionally regulates mTOR and contributes to cancer progression (Mura et al., 2015) by regulating cell division, apoptosis, and cell migration (Burrows et al., 2010). Here, MTOR is linked to cancer.
