The protein encoded by the mammalian lethal with SEC13 protein 8 (MLST8) gene, also known as G protein beta subunit-like (GBL), promotes tumor cell growth and development by regulating mTOR (mechanistic target of rapamycin) signaling and thus does not significantly affect normal cell growth (Kakumoto et al., 2015). Here, MLST8 is linked to neoplasm.
