The Raf-MEK-ERK pathway

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Oncology

Background:

  • The Raf-MEK-ERK signaling pathway regulates key cellular functions like proliferation, differentiation, and survival.
  • The precise mechanisms by which this pathway translates diverse extracellular signals into specific cellular responses are not fully understood.

Purpose of the Study:

  • To review the diverse physiological functions of Raf isozymes (A-Raf, B-Raf, Raf-1).
  • To explore how Raf isozyme diversity contributes to functional specificity within the Raf-MEK-ERK pathway.
  • To highlight the role of Raf isozymes in cancer development and progression.

Main Methods:

  • Literature review of recent findings on Raf isozymes.
  • Analysis of signaling pathway mechanisms.
  • Focus on cancer-related roles of Raf isoforms.

Main Results:

  • Raf family members (A-Raf, B-Raf, Raf-1) exhibit distinct physiological functions.
  • Isozyme diversity is crucial for specifying functional outcomes in cellular signaling.
  • Raf isozymes play significant roles in the context of cancer.

Conclusions:

  • Understanding Raf isozyme-specific functions is key to deciphering Raf-MEK-ERK pathway regulation.
  • Raf isozyme diversity contributes to the complexity of cellular signaling and biological outcomes.
  • Targeting specific Raf isozymes may offer novel therapeutic strategies for cancer.

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.
The mTOR pathway or the...
Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

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...
Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

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 the...
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...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

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 rapamycin-insensitive companion...
