**Background of GABPB2 Antibody**
The GABPB2 (GA-binding protein transcription factor beta subunit 2) antibody is a tool used to detect and study the GABPB2 protein, a critical component of the GA-binding protein (GABP) transcription factor complex. GABP, composed of alpha (GABPA) and beta (GABPB) subunits, belongs to the ETS family of transcription factors and regulates genes involved in mitochondrial biogenesis, cell cycle progression, and cellular metabolism. The beta subunit exists in two isoforms, GABPB1 and GABPB2. generated via alternative splicing. GABPB2 specifically modulates the DNA-binding affinity and transcriptional activity of the GABP complex.
Research using GABPB2 antibodies has highlighted its role in mitochondrial function, energy homeostasis, and cancer biology. For instance, GABPB2 dysregulation is implicated in tumorigenesis, including glioblastoma and non-small cell lung cancer, where it influences cell proliferation and apoptosis. The antibody is widely applied in techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to analyze protein expression, localization, and interactions in cellular and tissue samples.
Studies also link GABPB2 to neurological disorders, such as Parkinson’s disease, due to its regulatory role in mitochondrial genes. The availability of specific GABPB2 antibodies facilitates mechanistic insights into disease pathways and potential therapeutic targets, underscoring its importance in both basic and translational research.
