This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab199205 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.

Supplementary information

Rab4 also known as Ras-related protein Rab-4A is a small GTPase with a molecular mass of approximately 24 kDa. This protein is expressed in various cell types predominantly in tissues with high endocytic activity. Rab4 primarily functions as an endosome marker cooperating with the endocytic machinery to regulate sorting and recycling of endosomes. It occupies key positions on early endosomes relevant to its role in vesicular trafficking and membrane transportation. Endosome staining typically identifies Rab4 as an essential component in understanding endocytosis dynamics.
Biological function summary

Rab4 coordinates the trafficking of cargo between endosomes and the plasma membrane. It usually forms part of a protein complex that governs the recycling pathway of internalized membrane proteins and lipids. Rab4 modulates various cellular processes by impacting the rapid recycling of receptors receptors often return to the cell surface in response to Rab4 regulation. This action is important for maintaining cellular homeostasis and efficient signal transduction serving as a checkpoint for receptor-mediated events.

Pathways

The protein plays significant roles in the endocytic recycling pathway and the insulin signaling pathway. Rab4's activity influences the trafficking cycle often interacting with other proteins such as Rab11 and Rab5 to ensure efficient cargo movement within cells. By facilitating swift endosome recycling Rab4 has a direct impact on intracellular signaling and trafficking pathways supporting a range of cellular activities. This concerted interaction accentuates its importance in managing endosomal traffic and maintaining cellular connectivity.

Rab4 has implications in neurodegenerative disease and cancer. Abnormal Rab4 function disrupts endosomal signaling contributing to the pathogenesis of conditions like Alzheimer’s disease where it interacts with proteins such as amyloid precursor protein (APP). In cancer the dysregulation of Rab4-associated pathways affects tumor progression and metastasis. Rab4's connection with proteins like EGFR (Epidermal Growth Factor Receptor) indicates its potential role in altering cancer cell behaviors and resistance mechanisms making it a focus of interest in therapeutic approaches.

Target data

The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion (PubMed : 15907487, PubMed : 16034420). RAB4A is involved in protein transport (PubMed : 29425100). Also plays a role in vesicular traffic. Mediates VEGFR2 endosomal trafficking to enhance VEGFR2 signaling (PubMed : 29425100). Acts as a regulator of platelet alpha-granule release during activation and aggregation of platelets (By similarity).
