The Phospho-PBK (Y74) antibody is a specialized tool used to detect the phosphorylated form of PBK (PDZ-binding kinase), also known as TOPK (T-LAK cell-originated protein kinase), at tyrosine residue 74. PBK is a serine/threonine kinase belonging to the MAPKK family, primarily involved in regulating cell cycle progression, mitotic division, and DNA damage response. It is highly expressed in proliferating cells and certain cancers, where it promotes tumorigenesis by enhancing cell proliferation, survival, and metastasis. Phosphorylation at Y74 is a critical post-translational modification linked to PBK activation, which facilitates its interaction with downstream targets like p38 MAPK and contributes to its oncogenic functions.
This antibody is widely utilized in research to investigate PBK's role in cancer biology, particularly in malignancies such as breast cancer, glioblastoma, and colorectal cancer, where PBK overexpression correlates with poor prognosis. By specifically recognizing the phosphorylated Y74 epitope, the antibody enables the study of PBK activation dynamics in response to cellular stimuli or therapeutic interventions. Common applications include Western blotting, immunohistochemistry, and immunofluorescence, aiding in the assessment of PBK signaling status in cell lines, tissues, or preclinical models. Its specificity and reliability make it valuable for both mechanistic studies and potential diagnostic development, offering insights into PBK-driven pathways as targets for anticancer therapies.
