Receptor tyrosine kinases: from biology to pathology

Area of Science:

• Molecular biology
• Cell biology
• Biochemistry

Background:

• Receptor tyrosine kinases (RTKs) are transmembrane proteins crucial for cellular processes in metazoans.
• RTKs feature an extracellular ligand-binding domain, a transmembrane domain, and a conserved intracellular tyrosine kinase domain.
• Dysregulation of RTKs is implicated in numerous human diseases, including various cancers.

Purpose of the Study:

• To provide a comprehensive summary of human RTKs.
• To identify their cognate ligands and associated diseases.
• To discuss the potential of RTKs as therapeutic targets.

Main Methods:

• Literature review and data compilation.
• Classification of human RTKs based on extracellular domains.
• Analysis of mutations in the kinase domain and their disease relevance.

Main Results:

• Detailed overview of major human RTK families.
• Association of specific RTKs with particular ligands and disease phenotypes.
• Identification of RTKs with known mutations linked to cancer.

Conclusions:

• Human RTKs play critical roles in cellular functions and human health.
• RTK mutations are significant contributors to disease pathogenesis, particularly cancer.
• Targeting specific RTKs offers promising avenues for novel cancer therapies.
