Summary
Researchers created resources to study understudied kinases, vital for cell signaling and disease. These tools, including peptide libraries and chemical probes, are now available to advance dark kinase research.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- The human kinome comprises over 500 protein kinases essential for cellular signaling and implicated in various diseases.
- A significant portion of these kinases, approximately one-third, remain understudied, hindering a comprehensive understanding of their roles.
Purpose of the Study:
- To develop and provide novel resources for the in-depth investigation of understudied protein kinases.
- To facilitate research into the function and therapeutic targeting of kinases currently lacking extensive study.
Main Methods:
- Creation of a heavy amino acid peptide library for quantitative protein kinase expression analysis.
- Utilizing miniTurbo-biotin ligase tagging for proximity-dependent protein biotinylation to map kinase interaction networks.
- Development of NanoBRET probes for assessing chemical tool target specificity in live-cell assays.
- Characterization of small molecule inhibitors targeting understudied kinases.
- Application of computational tools to elucidate kinome architecture.
Main Results:
- A suite of resources has been generated, including quantitative assays, interaction mapping tools, and live-cell screening probes.
- Chemical tools and computational frameworks have been developed and characterized for understudied kinases.
- The Dark Kinase Knowledgebase has been established to centralize access to these valuable research assets.
Conclusions:
- The developed resources significantly enhance the capacity for studying understudied kinases.
- Increased accessibility to these tools via the Dark Kinase Knowledgebase will accelerate research into kinase function and disease mechanisms.
- This initiative aims to illuminate the roles of 'dark kinases' in biological processes and disease states.

3.6K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

6.3K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:22Amplifying Signals via Enzymatic Cascade
8.5K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

02:15M-Cdk Drives Transition Into Mitosis
5.6K
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

01:07MAPK Signaling Cascades
5.5K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
