Western blot - Anti-Rab4 antibody [EPR3042] - BSA and Azide free (AB247727)

This data was developed using the same antibody clone in a different buffer formation (ab108974).

Lanes 1- 2 : Merged signal (red and green). Green - ab108974 observed at 24 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab108974 was shown to react with Rab4 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab264781 (knockout cell lysate ab257624) was used. Wild-type HeLa and RAB4A knockout HeLa cell lysates were subjected to SDS-PAGE. ab108974 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 Dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

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.
