Spliceosome Structure and Function [PDF]

Cold Spring Harbor Perspectives in Biology, 2010
Pre-mRNA splicing is catalyzed by the spliceosome, a multimegadalton ribonucleoprotein (RNP) complex comprised of five snRNPs and numerous proteins. Intricate RNA-RNA and RNP networks, which serve to align the reactive groups of the pre-mRNA for catalysis, are formed and repeatedly rearranged during spliceosome assembly and catalysis.

A comprehensive proteome and phosphoproteome atlas across nine organs of the Chinese hamster

Animal Models and Experimental Medicine, EarlyView.
This study presents the first comprehensive proteome and phosphoproteome atlas of the Chinese hamster across nine organs (heart, liver, lung, kidney, spleen, cerebral cortex, skeletal muscle, stomach, and testis or ovary). A total of 14 219 proteins were identified in the proteome, with 11 828 phosphorylated proteins and 47 122 phosphorylation sites ...

Dysregulation of U12‐Type Splicing in Lupus Neutrophils

Arthritis &Rheumatology, EarlyView.
Objective Neutrophil dysfunction is a hallmark of systemic lupus erythematosus (SLE), but its molecular basis remains unclear. This study explores transcriptional and posttranscriptional changes in low‐density granulocytes (LDGs), a proinflammatory neutrophil subset expanded in SLE, focusing on NADPH oxidase (Nox) function and minor intron splicing ...

The nuclear GYF protein CD2BP2/U5–52K is required for T cell homeostasis

Frontiers in Immunology
The question whether interference with the ubiquitous splicing machinery can lead to cell-type specific perturbation of cellular function is addressed here by T cell specific ablation of the general U5 snRNP assembly factor CD2BP2/U5–52K.

Dynamics and consequences of spliceosome E complex formation

eLife, 2017
The spliceosome must identify the correct splice sites (SS) and branchsite (BS) used during splicing. E complex is the earliest spliceosome precursor in which the 5' SS and BS are defined.

The type 2C Ser/Thr phosphatase PP2C gamma is a pre-mRNA splicing factor [PDF]

, 1999
To identify activities involved in human pre-mRNA splicing, we have developed a procedure to separate HeLa cell nuclear extract into five complementing fractions.

Differential Proteomic Analysis to Reveal the Mechanism of Heat Damage in Soybean Using a Data‐Independent Acquisition (DIA) Strategy

Food Safety and Health, EarlyView.
Heat‐stressed soybeans adapt to elevated temperatures through coordinate regulation of destructive and protective protein expression ‐ suppressing detrimental proteins while enhancing beneficial ones. ABSTRACT Soybean represents the largest imported agricultural product in China. Imported soybeans are typically transported via maritime shipping. During

Proteomic insights into the invasiveness and tumor progression of non-functioning pituitary adenomas: A scoping review. [PDF]

J Neuroendocrinol
Abstract Nonfunctioning pituitary adenomas (NFPAs) are common intracranial tumors that, despite being histologically benign, can exhibit invasive growth, as well as postoperative tumor progression. Surgical resection is the primary treatment of choice; however, residual tumor tissue is frequently observed, with between 30% and 50% of these cases ...

Multi‐Cohort Analysis Reveals Genetic Predispositions to Clonal Hematopoiesis as Mutation‐Specific Risk Factors for Stroke

Advanced Genetics, Volume 6, Issue 1, March 2025.
This study comprehensively evaluated the differential effect of clonal hematopoiesis (CH) mutations on the risk of various stroke subtypes and functional recovery. It shows that TET2 is associated with small vessel stroke possibly via a pro‐inflammatory pathway. Abstract Recent observational studies have found an association between Clonal Hematopoesis
