The XKR6 antibody is a research tool designed to target the XKR6 protein, a member of the XK-related family implicated in cellular processes such as apoptosis and phospholipid scrambling. The XKR family, including XKR6. shares structural homology with the XK protein, which is linked to neurodegenerative disorders like McLeod syndrome. While XKR6’s precise biological role remains under investigation, studies suggest its involvement in phosphatidylserine externalization—a hallmark of apoptotic cells—and potential regulation of cell death signaling pathways. This antibody enables detection and analysis of XKR6 expression in various experimental models, aiding research into its function in physiological and pathological contexts, such as cancer or immune regulation. Despite progress, the mechanistic details of XKR6 activity, including its interaction partners and tissue-specific roles, require further elucidation. Current applications of the XKR6 antibody include Western blotting, immunohistochemistry, and flow cytometry, supporting both basic research and translational studies exploring its utility as a biomarker or therapeutic target. Ongoing efforts aim to clarify its contribution to cellular homeostasis and disease, positioning XKR6 as a protein of growing interest in cell biology and biomedicine.
