背景信息

The Myc (Phospho-Thr58) antibody is designed to detect Myc protein phosphorylated at threonine 58 (Thr58), a critical post-translational modification site in the Myc family of transcription factors. Myc proteins (c-Myc, N-Myc, and L-Myc) regulate cell proliferation, differentiation, apoptosis, and metabolism by controlling the expression of target genes. Phosphorylation at Thr58. located within the Myc N-terminal transactivation domain, is a key regulatory mechanism influencing Myc protein stability and activity. This modification is mediated by glycogen synthase kinase 3 beta (GSK3β) following priming phosphorylation at Ser62. Thr58 phosphorylation promotes Myc ubiquitination and subsequent proteasomal degradation via the SCFFbw7 E3 ubiquitin ligase complex, thereby modulating Myc's oncogenic potential. Dysregulation of Thr58 phosphorylation is implicated in Myc-driven tumorigenesis, as stabilizing mutations at this site (e.g., Thr58→Ile mutations) are frequently observed in cancers. The Myc (Phospho-Thr58) antibody is widely used in research to investigate Myc phosphorylation dynamics, protein turnover mechanisms, and signaling pathways involving GSK3β or PI3K/AKT. It serves as a tool to study Myc's role in cancer biology, stem cell regulation, and therapeutic targeting. Specificity is typically validated using phosphorylation-deficient mutants or phosphatase-treated lysates.
