The p73 protein, a member of the p53 tumor suppressor family, plays critical roles in regulating cell cycle arrest, apoptosis, and differentiation. Unlike p53. p73 exists as multiple isoforms due to alternative promoter usage and splicing, resulting in two main groups: full-length transactivation-competent isoforms (TAp73) and N-terminally truncated variants (ΔNp73) that act as dominant-negative inhibitors. The p73(Ab-99) antibody is a monoclonal antibody specifically developed to recognize the N-terminal region of human p73α, detecting both TAp73 and ΔNp73 isoforms. Generated using a synthetic peptide corresponding to amino acids 1-80 of human p73. it has been widely employed in various applications including Western blotting, immunohistochemistry (IHC), and immunocytochemistry (ICC).
Originally characterized in cancer research, this antibody has helped elucidate p73's dual roles in tumorigenesis – acting as a tumor suppressor in certain contexts while promoting oncogenic activities in others. Studies using p73(Ab-99) have revealed its involvement in neuroblastoma differentiation, chemoresistance in colorectal cancer, and regulatory cross-talk with p53 family members. Its specificity for human p73 (without cross-reactivity with p53 or p63) makes it particularly valuable for distinguishing p73-specific signaling in complex biological systems. However, users should validate its performance across experimental models, as isoform expression patterns vary significantly between tissues and disease states.
