Functional coupling of transcription and splicing

Marta MontesCarlos Suñé


The tightly regulated process of precursor messenger RNA (pre-mRNA) alternative splicing is a key mechanism to increase the number and complexity of proteins encoded by the genome. Evidence gathered in recent years has established that transcription and splicing are physically and functionally coupled and that this coupling may be an essential aspect of the regulation of splicing and alternative splicing. Recent advances in our understanding of transcription and of splicing regulation have uncovered the multiple interactions between components from both types of machinery. These interactions help to explain the functional coupling of RNAPII transcription and pre-mRNA alternative splicing for efficient and regulated gene expression at the molecular level. Recent technological advances, in addition to novel cell and molecular biology approaches, have led to the development of new tools for addressing mechanistic questions to achieve an integrated and global understanding of the functional coupling of RNAPII transcription and pre-mRNA alternative splicing. Here, we review major milestones and insights into RNA polymerase II transcription and pre-mRNA alternative splicing as well as new concepts and challenges that have arisen from...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Cell Checkpoints & Regulators

Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.

Alternative splicing

Alternative splicing a regulated gene expression process that allows a single genetic sequence to code for multiple proteins. Here is that latest research.


Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cell Adhesion Molecules in the Brain

Cell adhesion molecules found on cell surface help cells bind with other cells or the extracellular matrix to maintain structure and function. Here is the latest research on their role in the brain.
