c-Myc DNA binding protein structure
Structural highlights
FunctionRBMS1_HUMAN Single-stranded DNA binding protein that interacts with the region upstream of the MYC gene. Binds specifically to the DNA sequence motif 5'-[AT]CT[AT][AT]T-3'. Probably has a role in DNA replication. Publication Abstract from PubMedDNA binding proteins recognize DNA specifically or non-specifically using direct and indirect readout mechanisms like sliding, hopping, and diffusion. However, a common difficulty in explicitly elucidating any particular mechanism of site-specific DNA-protein recognition is the lack of knowledge regarding target sequences and inadequate account of non-specific interactions, in general. Here, we decipher the structural basis of target search performed by the key regulator of expression of c-myc proto-oncogene, the human RBMS1 protein. In this study, we have shown the structural reorganization of this multi-domain protein required for recognizing the specific c-myc promoter sequence. The results suggest that a synergy between structural re-organization and thermodynamics is necessary for the recognition of target sequences. The study presents another perspective of looking at the DNA-protein interactions.
