DNA Recognition by Helix-Loop-Helix Proteins,of variable length, and amino acid composition and sequence. These motifs dimerize by approximating the conserved hydrophobic faces of the α-helices, forming a left-handed, parallel, four-helix bundle. Baltimore and coworkers (Murre et al. 1989) first described conservation of this feature in a larg

Nuclear Pre-mRNA Splicing,are present in the precursor mRNA (pre-mRNA) molecule and subsequent ligation of the flanking, functional sequences (i.e., exons). Pre-mRNA splicing is thus a critical step in the long chain of events required for the expression of a large number of eukaryotic genes. In a number of instances, the sp
