RNA binding of T-cell intracellular antigen-1 (TIA-1) C-terminal RNA recognition motif is modified by pH conditions
Description
Background: T-cell intracellular antigen- 1(TIA-1) is a key DNA/RNA binding protein in RNA metabolism. Results: The binding of TIA-1 RRM3 domain (isolated or fused to RRM2) to RNA is affected by pH changes. Conclusion: The pH-dependence of RRM3/RNA interaction may have a significant effect in the overall TIA-1 function. Significance: Unveiling the auxiliary role of RRM3 in RNA recognition sheds light on the TIA-1 function between cell compartments changes due to the protonation / deprotonation of TIA-1 RRM3 histidine residues. The auxiliary role of the Cterminal RRM3 domain in TIA-1 RNA recognition is poorly understood and this work provides an insight into its binding mechanisms
