Depletion of the Poly(C)-binding Proteins αCP1 and αCP2 from K562 Cells Leads to p53-independent Induction of Cyclin-dependent Kinase Inhibitor (CDKN1A) and G1 Arrest

12 Feb 2009

Abstract excerpt

The alpha-globin poly(C)-binding proteins (alphaCPs) comprise an abundant and widely expressed set of K-homolog domain RNA-binding proteins. alphaCPs regulate the expression of a number of cellular and viral mRNAs at the levels of splicing, stability, and translation. Previous surveys have identified 160 mRNAs that are bound by alphaCP in the human hematopoietic cell line, K562. To explore the functions of these...
