Abstract:
The dynamic rearrangements of RNA and protein complexes and the fidelity of pre-mRNA splicing are governed by DExD/H-box ATPases. One of the spliceosomal ATPases, Brr2, is believed to facilitate conformational rearrangements during spliceosome activation and disassembly. It features an unusual architecture, with two consecutive helicase-cassettes, each comprising a helicase and a Sec63 domain. Only the N-terminal cassette exhibits catalytic activity. By contrast, the C-terminal half of Brr2 engages in protein interactions. Amongst interacting proteins are the Prp2 and Prp16 helicases. The work

Abstract:
P68 is a prototypical member of the DEAD box RNA helicase family. Implicated in numerous functions such as cell proliferation, cancer metastasis, transcription regulation and pre-mRNA spllicing, p68 is a multifunctional protein whose roles are still not completely understood. In the studies presented, we found that p68 was an important regulator of numerous cancer related genes. This study focuses on the cancer related genes Snail and hTERT. We show that p68 binds to the promoter and a downstream region within each gene, suggesting that p68 operates via the same mechanism with both genes.

Abstract:
The essential protein Mtr4 is a conserved Ski2-like RNA helicase that maintains the integrity of nuclear RNA by promoting the 3' end decay of a wide variety of RNA substrates. Mtr4 activates the multi-protein exosome in RNA processing, surveillance, and turnover pathways by unwinding secondary structure and/or displacing associated proteins from RNA substrates. While Mtr4 may be able to promote decay independently, it is often associated with large multi-protein assemblies. Specifically, Mtr4 is the largest member of the TRAMP (Trf4/Air2/Mtr4 polyadenylation) complex which targets a plethora o

Abstract:
How tumor cells migrate and metastasize from primary sites requires four major steps: invasion, intravasation, extravasation and proliferation from micrometastases to malignant tumor. The initiation of tumor cell invasion requires Epithelial-Mesenchymal Transition (EMT), by which tumor cells lose cell-cell interactions and gain the ability of migration. The gene expression profile during the EMT process has been extensively investigated to study the initiation of EMT. In our studies, we indicated that tyrosine phosphorylation of human p68 RNA helicase positively associated with the malignant

Dividing cells are constantly under threat from both endogenous and exogenous DNA damaging stresses that can lead to mutations and structural variations in DNA.

Though R-loops are known to induce DNA damage and DNA replication stress, it is unclear whether they are recognized and processed by an established DNA repair pathway prior to inducing DNA breaks. Canonically, DNA repair proteins work downstream of R-loop-induced DNA damage to stimulate repair and suppress genome instability. Recently, the

P68 RNA helicase (p68), as a DEAD family protein, is a typical RNA helicase protein. P68 functions in many other biological processes, which include the regulations of the gene transcription, cell proliferation and cell differentiation. In our group, Y593 phosphorylated p68 was found to have a function in the epithelial mesynchymal transition, which is an important process for cancer metastasis. In the present study, we found that p68 is a nucleocytoplasmic shuttling protein. The protein carries two functional nuclear exporting signal sequences and two nuclear localization signal sequences.
