The tumor suppressor PCBP1, which is mainly localized in the nucleus and cytoplasm, represses tumorigenesis and metastasis through regulating transcription, alternative splicing, RNA stability and translation of tumor‐related genes.[39, 40] However, the regulation of PCBP1 localization and posttranslational modification in the cytoplasm is still vague. The gene discussed is PCBP1; the disease is neoplasm.
