Fig. 8. Schematic summary shows that FBXL6 promotes CRC growth by degrading phospho-p53 (S315).

In CRCs, high-level FBXL6 driven by gene amplification promotes phospho-p53 (S315) degradation. AURKA and CDK16 along with other kinases may mediate p53 (S315) phosphorylation. The loss of p53 helps to promote CRC development and or its survival.
