The RBMXL3 antibody is a research tool designed to detect the RNA-binding motif protein X-linked-like 3 (RBMXL3), a member of the RNA-binding protein family. RBMXL3 shares homology with RBMX and RBMY, proteins implicated in RNA processing, splicing, and germ cell development. While RBMX is ubiquitously expressed and involved in maintaining RNA stability, and RBMY is critical for male germ cell maturation, RBMXL3's exact biological role remains less defined. Studies suggest it may participate in RNA metabolism during spermatogenesis or early embryogenesis, potentially compensating for RBMY in non-gonadal tissues or female cells. The antibody is commonly used in techniques like Western blotting, immunohistochemistry, or immunofluorescence to study RBMXL3's expression patterns, subcellular localization, and interactions. Its applications span reproductive biology, cancer research (particularly germ cell tumors), and investigations into RNA regulation mechanisms. However, commercial availability and validation data remain limited, requiring careful optimization in experimental settings. Researchers utilize this antibody to explore RBMXL3's potential links to infertility, developmental disorders, or dysregulated RNA processing in disease contexts.
