This review explores how structural biology reveals new mechanisms controlling Golgi complex protein transport. It details how Arf and Rab GTPase activation, cargo sorting, and vesicle tethering ensure cellular traffic efficiency.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Structural Biology

Background:

  • The Golgi complex acts as a central sorting station in eukaryotic cells.
  • Multiple trafficking pathways manage protein transport between the Golgi, endoplasmic reticulum, plasma membrane, and endolysosomal system.

Purpose of the Study:

  • To review recent structural biology studies on Golgi trafficking mechanisms.
  • To elucidate novel cellular controls over protein transport through the Golgi.

Main Methods:

  • Utilizing structural biology approaches.
  • Analyzing recent research findings on Golgi complex function.

Main Results:

  • Recent studies reveal insights into Arf and Rab GTPase activation regulation.
