A Specific Isoform of hnRNP D Interacts with DNA in the LR1 Heterodimer: Canonical RNA Binding Motifs in a Sequence-specific Duplex DNA Binding Protein

1 Nov 1998

Abstract excerpt

The B cell-specific, sequence-specific duplex DNA-binding protein LR1 is a transcriptional activator and may also function in heavy chain class switch recombination. LR1 is composed of two polypeptides, a 106-kDa subunit that is nucleolin, and a 45-kDa subunit that we now show to be a specific isoform of hnRNP D. hnRNP D and nucleolin both contain canonical RNA binding domains (RBDs also called RRMs) and...
