Abstract:
Receptor tyrosine kinases and other cell surface receptors are tightly regulated by endocytosis, which controls both the duration and spatial organisation of their downstream signalling. In cancers, altered internalisation and trafficking lead to sustained or misrouted signalling that promotes uncontrolled cell growth and survival. Motor proteins and their cargo adaptors are central to receptor signalling since they determine intracellular endosome positioning, recycling, and degradation. While their roles in intracellular transport have long been studied, the dysfunction of motors and adaptors in the context of aberrant receptor signalling and cancer progression has only recently begun to emerge. In this review, we highlight recent advances in understanding motor and adaptor function in healthy cells, discuss evidence implicating these proteins in oncogenic signalling, and consider how these insights may guide future directions in the field.
Insights
Receptor endocytosis regulates cell signalling. Motor proteins and adaptors, crucial for this process, are increasingly implicated in cancer when their function is disrupted, driving uncontrolled cell growth.
Area of Science:
- Cell Biology
- Molecular Biology
- Cancer Research
Background:
- Cell surface receptor signalling is tightly regulated by endocytosis.
- Aberrant receptor internalisation and trafficking in cancer promote uncontrolled cell growth.
- Motor proteins and cargo adaptors are key regulators of intracellular transport and receptor signalling.
Purpose of the Study:
- To review recent advances in understanding motor and adaptor protein function in healthy cells.
- To discuss evidence implicating these proteins in oncogenic signalling.
- To explore future directions for targeting these proteins in cancer therapy.
Main Methods:
- Literature review of recent scientific publications.
- Analysis of studies on receptor tyrosine kinases and endocytosis.
- Examination of research on motor proteins and adaptor proteins in cancer.
Main Results:
- Motor proteins and adaptors play critical roles in endosome positioning, recycling, and degradation.
- Dysfunction of these proteins contributes to sustained or misrouted signalling in cancer.
- Emerging evidence links motor and adaptor protein abnormalities to cancer progression.
Conclusions:
- Understanding motor and adaptor protein roles in healthy cells is crucial.
- Their dysfunction represents a significant factor in oncogenic signalling.
- Targeting these proteins offers potential new avenues for cancer treatment.
