Insights

The MoKCa database structurally annotates cancer-associated protein kinase mutations. This resource aids researchers in understanding mutation consequences for developing targeted cancer therapies.

Area of Science:

  • Biochemistry
  • Genetics
  • Oncology

Background:

  • Protein kinases are frequently mutated in human cancers.
  • Mutated and activated protein kinases are key targets for anticancer drug development.

Purpose of the Study:

  • To develop the MoKCa database for structural and functional annotation of protein kinase mutations in cancer.
  • To predict phenotypic consequences of these mutations.

Main Methods:

  • Somatic mutation data from tumors and cell lines were mapped onto protein crystal structures.
  • Mutated amino acid positions were visualized on sequence-based pictograms and 3D structures.
  • Interactive molecular graphics were integrated for viewing mutation data.

Main Results:

  • The MoKCa database provides expert annotations on the functional implications of mutations.
  • Proteins are linked to functional resources and annotated with structural features like domains and phosphorylation sites.
  • The database integrates assessments from multiple sources for cancer-associated mutations.

Conclusions:

  • MoKCa facilitates authoritative annotation of cancer-related mutations for biologists.
  • The database aids in understanding the molecular and functional impact of kinase mutations in cancer.
  • It supports the generation and analysis of new mutational data for cancer research.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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.

M-Cdk Drives Transition Into Mitosis02:15

M-Cdk Drives Transition Into Mitosis

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.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

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...
The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a superfamily...
Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Mutations in Microorganisms01:18

Mutations in Microorganisms

Mutations are heritable changes in an organism’s genome involving alterations in the base sequence of DNA or RNA. These changes can influence cellular processes and phenotypic traits, potentially transforming the unaltered wild type into a mutant form. Such changes, termed forward mutations, are pivotal in shaping the genetic diversity of organisms.RNA viruses exhibit the highest mutation rates due to the absence of robust proofreading mechanisms during genome replication. In contrast,...
