SRSF5 and neoplasm: SRSF5 (Serine and arginine-rich splicing factor 5), a member of the serine/arginine (SR)-rich family of pre-mRNA splicing factors, promotes the production of CCAR1S proteins by alternative splicing CCAR1 which enhances glucose consumption and acetyl-coA production, thus promoting tumor growth (Chen et al., 2018).
