Insights

RAB25 protein, a member of the rat sarcoma (RAS) family, is linked to ovarian and breast cancer development. Its function in endosomal transport may promote tumor aggressiveness, offering new insights into cancer pathways.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • RAB25 is a small GTPase protein belonging to the rat sarcoma (RAS) family.
  • This protein has been implicated in the pathological processes of various cancers, including ovarian and breast cancer.

Purpose of the Study:

  • To review the association between RAB25 and cancer development.
  • To summarize current knowledge on the potential roles of RAB25 in various types of cancer.

Main Methods:

  • Literature review of studies investigating RAB25 in cancer.
  • Analysis of RAB25's role in endosomal transport and receptor recycling.
  • Examination of structural variations and post-translational modifications of RAS superfamily proteins.

Main Results:

  • RAB25's involvement in endosomal transport and recycling of cell-surface proteins is a key mechanism.
  • This function can disrupt cellular pathways, potentially promoting tumor development and aggressiveness.
  • Variations in RAS proteins influence their subcellular localization and downstream effector recruitment.

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:
Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
Rab Cascades01:25

Rab Cascades

Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.
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.

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins, also known...
