Disruption of pre-mRNA splicing in vivo results in reorganization of splicing factors [PDF]

, 1994
We have examined the functional significance of the organization of pre-mRNA splicing factors in a speckled distribution in the mammalian cell nucleus. Upon microinjection into living cells of oligonucleotides or antibodies that inhibit pre-mRNA splicing

Promising Prodiginins Biological Activities

Chemistry &Biodiversity, EarlyView.
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

Distribution of Troy (Tnfrsf19) in the Gastric Gland During Postnatal Development: Effects of Early Weaning

Cell Biology International, EarlyView.
ABSTRACT This study investigates the distribution and role of the stem cell marker Troy (Tnfrsf19) in the gastric mucosa of rats during postnatal development and the effects of early weaning. Troy, previously identified as a reserve stem cell marker in adult gastric tissues, is examined across various developmental stages from birth to adulthood.

RNA Structural Requirements for the Association of the Spliceosomal hPrp31 Protein with the U4 and U4atac Small Nuclear Ribonucleoproteins*

Journal of Biological Chemistry, 2006
The kink-turn, a stem I-internal loop-stem II structure of the 5 ′ stem-loop of U4 and U4atac small nuclear (sn) RNAs bound by 15.5K protein is required for binding of human Prp31 protein (hPrp31) during U4 and U4atac snRNP assembly. In box C/D snoRNPs a

Spinal Muscular Atrophy: From Defective Chaperoning of snRNP Assembly to Neuromuscular Dysfunction

Frontiers in Molecular Biosciences, 2017
Spinal Muscular Atrophy (SMA) is a neuromuscular disorder that results from decreased levels of the survival motor neuron (SMN) protein. SMN is part of a multiprotein complex that also includes Gemins 2–8 and Unrip. The SMN-Gemins complex cooperates with

PARP-1 dependent recruitment of the amyotrophic lateral sclerosis-associated protein FUS/TLS to sites of oxidative DNA damage [PDF]

, 2013
Amyotrophic lateral sclerosis (ALS) is associated with progressive degeneration of motor neurons. Several of the genes associated with this disease encode proteins involved in RNA processing, including fused-in-sarcoma/translocated-in-sarcoma (FUS/TLS ...

A novel EB-1/AIDA-1 isoform, AIDA-1c, interacts with the Cajal body protein coilin

BMC Cell Biology, 2005
Background Cajal bodies (CBs) are nuclear suborganelles that play a role in the biogenesis of small nuclear ribonucleoproteins (snRNPs), which are crucial for pre-mRNA splicing.

Composition of the Survival Motor Neuron (SMN) complex in Drosophila melanogaster [PDF]

, 2018
Spinal Muscular Atrophy (SMA) is caused by homozygous mutations in the human survival motor neuron 1 (SMN1) gene. SMN protein has a well-characterized role in the biogenesis of small nuclear ribonucleoproteins (snRNPs), core components of the spliceosome.
