X-ray structure of gene product from homo sapiens Hs.433573

Overview

The crystal structure of the human basophilic leukemia-expressed protein, (BLES03, p5326, Hs.433573) was determined by single-wavelength anomalous, diffraction and refined to an R factor of 18.8% (Rfree = 24.5%) at 2.5 A, resolution. BLES03 shows no detectable sequence similarity to any, functionally characterized proteins using state-of-the-art, sequence-comparison tools. The structure of BLES03 adopts a fold similar, to that of eukaryotic transcription initiation factor 4E (eIF4E), a, protein involved in the recognition of the cap structure of eukaryotic, mRNA. In addition to fold similarity, the electrostatic surface potentials, of BLES03 and eIF4E show a clear conservation of basic and acidic patches., In the crystal lattice, the acidic amino-terminal helices of BLES03, monomers are bound within the basic cavity of symmetry-related monomers in, a manner analogous to the binding of mRNA by eIF4E. Interestingly, the, gene locus encoding BLES03 is located between genes encoding the proteins, DRAP1 and FOSL1, both of which are involved in transcription initiation., It is hypothesized that BLES03 itself may be involved in a biochemical, process that requires recognition of nucleic acids.
