The Telomerase/Vault-Associated Protein Tep1 Is Required for Vault RNA Stability and Its Association with the Vault Particle

Vaults and telomerase are ribonucleoprotein (RNP) particles that share a common protein subunit, TEP1. Although its role in either complex has not yet been defined, TEP1 has been shown to interact with the mouse telomerase RNA and with several of the human vault RNAs in a yeast three-hybrid assay. An mTep1(-/-) mouse was previously generated which resulted in no apparent change in telomere leng...

NKAP is a novel RS-related protein that interacts with RNA and RNA binding proteins

NKAP is a highly conserved protein with roles in transcriptional repression, T-cell development, maturation and acquisition of functional competency and maintenance and survival of adult hematopoietic stem cells. Here we report the novel role of NKAP in splicing. With NKAP-specific antibodies we found that NKAP localizes to nuclear speckles. NKAP has an RS motif at the N-terminus followed by a ...

The RNA binding protein Hfq interacts specifically with tRNAs.

Hfq is an RNA binding protein that has been studied extensively for its role in the biology of small noncoding RNAs (ncRNAs) in bacteria, where it facilitates post-transcriptional gene regulation during stress responses. We show that Hfq also binds with high specificity and nanomolar affinity to tRNAs despite their lack of a canonical A/U rich single-stranded sequence. This affinity is comparab...

A novel RNA-binding nuclear protein that interacts with the fragile X mental retardation (FMR1) protein.

Silenced expression of the FMR1 gene is responsible for the fragile X syndrome. The FMR1 gene codes for an RNA binding protein (FMRP), which can shuttle between the nucleus and the cytoplasm and is found associated to polysomes in the cytoplasm. By two-hybrid assay in yeast, we identified a novel protein interacting with FMRP: nuclear FMRP interacting protein (NUFIP). NUFIP mRNA expression is s...

Expression of the vault RNA protects cells from undergoing apoptosis

Non-protein-coding RNAs are a functionally versatile class of transcripts exerting their biological roles on the RNA level. Recently, we demonstrated that the vault complex-associated RNAs (vtRNAs) are significantly upregulated in Epstein-Barr virus (EBV)-infected human B cells. Very little is known about the function(s) of the vtRNAs or the vault complex. Here, we individually express latent E...
