Variants of the CD44 cell-surface adhesion molecule include additional sequences encoded by combinations of exons from the membrane proximal domain (exons 6-14). Preliminary studies suggest that these additional variable membrane proximal sequences may alter the ligand specificity, glycosylation, and biologic function of CD44. In earlier studies, we found that primary extranodal and widely diss...
The exon junction complex (EJC) plays a major role in posttranscriptional regulation of mRNA in metazoa. The EJC is deposited onto mRNA during splicing and is transported to the cytoplasm where it influences translation, surveillance, and localization of the spliced mRNA. The complex is formed by the association of four proteins (eIF4AIII, Barentsz [Btz], Mago, and Y14), mRNA, and ATP. The 2.2 ...
Nonsense-mediated mRNA decay (NMD) is a surveillance mechanism that detects and degrades mRNAs containing premature termination codons (PTCs). SMG-1-mediated Upf1 phosphorylation takes place in the decay inducing complex (DECID), which contains a ribosome, release factors, Upf1, SMG-1, an exon junction complex (EJC) and a PTC-mRNA. However, the significance and the consequence of Upf1 phosphory...
In eukaryotes, RNA processing events in the nucleus influence the fate of transcripts in the cytoplasm. The multi-protein exon junction complex (EJC) associates with mRNAs concomitant with splicing in the nucleus and plays important roles in export, translation, surveillance and localization of mRNAs in the cytoplasm. In mammalian cells, the ribosome associated protein PYM (HsPYM) binds the Y14...
Hyperphosphorylation and dysregulation of exon 10 splicing of Tau are pivotally involved in pathogenesis of Alzheimer disease (AD) and/or other tauopathies. Alternative splicing of Tau exon 10, which encodes the second microtubule-binding repeat, generates Tau isoforms containing three and four microtubule-binding repeats, termed 3R-Taus and 4R-Taus, respectively. Dual specificity tyrosine-phos...
The XPD gene product has a dual function in basal transcription and in nucleotide excision repair. We have previously reported that two polymorphisms in the gene, one silent mutation in codon 156 of exon 6 and one giving rise to a Lys-->Gln substitution in codon 751 of exon 23, showed signs of being associated with basal cell carcinoma in a Scandinavian study group of psoriasis patients and non...
OBJECTIVE Mutations in the RET gene are responsible for hereditary medullary thyroid cancer (MTC) and may vary between ethnic groups. We report the spectrum of mutations detected in patients with MTC in a referral center in Greece. PATIENTS AND METHODS Screening for RET mutations was performed in 313 subjects from 188 unrelated families: 51 patients had clinical suspicion for familial disease...
