Insights

The SRC tyrosine kinase (SRC) is crucial for cell signaling and growth. Deregulated SRC drives cancer, and new phosphoproteomic insights reveal its mechanisms, aiding targeted cancer therapies.

Area of Science:

  • Cellular Biology
  • Molecular Oncology
  • Biochemistry

Background:

  • The SRC tyrosine kinase (SRC) is a key regulator of signal transduction pathways initiated by cell-surface receptors.
  • SRC plays a critical role in cell growth, migration, and survival.
  • Deregulated SRC activity is implicated in human cancer development and progression.

Purpose of the Study:

  • To review the impact of phosphoproteomic methods on understanding SRC signaling mechanisms.
  • To explore the role of SRC in normal and tumor cells.
  • To discuss therapeutic strategies targeting SRC signaling in cancer.

Main Methods:

  • Review of phosphoproteomic studies identifying SRC substrates.
  • Analysis of SRC's role in receptor tyrosine kinase (RTK) signaling.
  • Integration of findings for therapeutic strategy development.

Main Results:

  • Phosphoproteomics has significantly expanded the known SRC substrate repertoire.
  • SRC promotes RTK-mediated signaling, contributing to oncogenesis even without external stimuli.
  • SRC deregulation is a common event in human cancers.

Conclusions:

  • Novel insights from phosphoproteomics are refining our understanding of SRC signaling pathways.
  • Targeting SRC signaling presents a promising therapeutic avenue for various human cancers.
  • Further research into SRC substrates and regulation is vital for effective cancer treatment.

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.

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.

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...

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
