HNRNPA1 and cancer: Heterogeneous nuclear ribonucleoprotein A1 (HNRNPA1) is highly expressed in a variety of cancers and closely associated with cancer initiation and progression.208–210 P300-mediated lysine crotonylation of HNRNPA1 helps to upregulate its protein expression, which in turn promotes HeLa cell proliferation, invasion, and migration.211 However, whether crotonylation hampered HNRNPA1 ubiquitination and degradation to enhance its protein stability still needs to be investigated.
