The inclusion of exon 16 in the mature protein 4.1R messenger RNA (mRNA) is a critical event in red blood cell membrane biogenesis. It occurs during late erythroid development and results in inclusion of the 10-kd domain needed for stabilization of the spectrin/actin lattice. In this study, an experimental model was established in murine erythroleukemia(More)
An increasing number of genomic variations are no more regarded as harmless changes in protein coding sequences or as genetic polymorphisms. Studying the impact of these variations on mRNA metabolism became a central issue to better understand the biological significance of disease. We describe here a severe congenital muscular dystrophy (CMD) with lumbar(More)
SR proteins exhibit diverse functions ranging from their role in constitutive and alternative splicing, to virtually all aspects of mRNA metabolism. These findings have attracted growing interest in deciphering the regulatory mechanisms that control the tissue-specific expression of these SR proteins. In this study, we show that SRSF5 protein decreases(More)
BACKGROUND Tyrosinemia type I, the most severe disease of the tyrosine catabolic pathway is caused by a deficiency in fumarylacetoacetate hydrolase (FAH). A patient showing few of the symptoms associated with the disease, was found to be a compound heterozygote for a splice mutation, IVS6-1g->t, and a putative missense mutation, Q279R. Analysis of FAH(More)
PURPOSE Recessive mutations of the myosin VIIA (MYO7A) gene are reported to be responsible for both a deaf-blindness syndrome (Usher type 1B [USH1B] and atypical Usher syndrome) and nonsyndromic hearing loss (HL; Deafness, Neurosensory, Autosomal Recessive 2 [DFNB2]). The existence of DFNB2 is controversial, and often there is no relationship between the(More)
Protein 4.1 has been defined as a major component of the subcortical skeleton of erythrocytes. It binds the spectrin-actin scaffold through a 10-kD internal domain. This binding requires an essential 21-amino acid sequence motif, Motif I, which is retained by alternative splicing at the late stage of erythroid differentiation. We here analyze the molecular(More)
The intron removal during the pre-mRNA splicing in higher eukaryotes requires the accurate identification of the two splice sites at the ends of the exons, or exon definition. However, the consensus sequences at the splice sites provide insufficient information to distinguish true splice sites from the large number of the false ones that populate the(More)
