p53 (cynomolgus monkey) Monoclonal Antibody (Clone 06)

p53 is a transcription factor and tumor suppressor encoded by TP53 in humans with roles in cell cycle arrest, apoptosis, senescence, differentiation, and DNA repair.^1,2 It is composed of two N-terminal intrinsically disordered transactivation domains (TADs), a proline-rich domain (PRD), a DNA-binding domain (DBD), a tetramerization domain (TD), and an intrinsically disordered C-terminal domain.¹ p53 is ubiquitously expressed, with protein levels increasing under conditions of extra- or intracellular stress, such as DNA damage, oncogene activation, oxidative stress, or hypoxia.³ It is activated and translocated to the nucleus in response to cellular stress via post-translational modifications, such as phosphorylation, methylation, and acetylation, where it binds p53 consensus DNA-binding elements and regulates transcription of its target genes in a cell-, tissue-, and stress signal type-specific manner.^1,3 Loss-of-function and/or gain-of-function mutations in TP53 occur in approximately 50% of human cancers.² Cayman’s p53 (cynomolgus monkey) Monoclonal Antibody (Clone 06) can be used for ELISA and Western blot (WB) applications.
