WD Repeat And FYVE Domain-Containing Protein 4 (WDFY4) Antibody

Background

WD repeat and FYVE domain containing 4 (WDFY4), like WDFY3, is a protein that features WD repeats and a FYVE domain, which suggest its role in protein-protein interactions and endosomal trafficking. The FYVE domain in WDFY4 specifically binds phosphoinositides, a type of lipid critical for the regulation of vesicle trafficking and cellular membrane dynamics. Through its interaction with these lipids, WDFY4 is involved in the sorting of proteins within the endosomal system and the regulation of receptor recycling. This function is essential for maintaining proper cellular signaling, receptor downregulation, and protein degradation. WDFY4 also plays a role in regulating autophagy, a process crucial for maintaining cellular homeostasis by degrading and recycling damaged or unnecessary components. Moreover, WDFY4's involvement in immune function has been noted, with potential implications in diseases affecting immune responses and inflammatory processes. Given its critical role in vesicular trafficking and autophagy, disruptions in WDFY4's function could lead to disorders such as neurodegenerative diseases and autoimmune conditions. Understanding the full scope of WDFY4's role in cellular trafficking and immune regulation is essential for identifying novel therapeutic targets in related diseases.
