Zebrafish Pi4kb Antibody / Phosphatidylinositol 4-kinase beta

In zebrafish, Pi4kb is an ortholog of the human PI4KB gene. Both zebrafish and human Pi4kb share substantial sequence conservation and functional similarities, particularly in their roles in lipid signaling and membrane trafficking. The high degree of conservation between species makes zebrafish an ideal model for studying the molecular function of Pi4kb in cellular signaling, membrane dynamics, and vesicular trafficking. Zebrafish Pi4kb is highly expressed in tissues with high demands for membrane turnover and vesicular trafficking, such as the brain, heart, and muscle. The protein plays a significant role in the formation and function of membrane-bound organelles, including endosomes, lysosomes, and the Golgi apparatus. It also regulates the recycling of phosphoinositides, which are essential for maintaining the integrity of cellular membranes and signal transduction pathways. The Pi4kb gene in zebrafish has isoforms, which may differ in their tissue distribution and functional roles. These isoforms are thought to be important for the fine-tuned regulation of lipid signaling in different cell types and under varying physiological conditions. Isoform variation is likely linked to developmental stages and differentiation processes, particularly in tissues that require rapid changes in membrane composition. Given its essential role in membrane dynamics, lipid signaling, and vesicular trafficking, zebrafish Pi4kb is an important model for studying diseases related to membrane dysfunction, neurological disorders, and metabolic diseases. Its role in regulating phosphoinositide metabolism also makes it a valuable target for research into diseases such as cancer, cardiovascular disorders, and neurodegenerative diseases.
