Anti-Pbx3b monoclonal antibody
Researchers in the laboratory of Dr. Michael Cleary at Stanford University have developed anti-Pbx3b monoclonal antibodies to study transcriptional regulation and embryonic development. Pbx proteins comprise a set of four TALE (three amino acid loop extension) class homeodomain transcription factors that are implicated in developmental gene expression. They form hetero-oligomeric DNA-binding complexes and function as transcriptional regulators in cells of different developmental lineages.
Pbx3 is expressed in high levels predominantly in the developing central nervous system, including a region of the medulla oblongata that is implicated in the control of respiration. Pbx3-deficient mice die within a few hours of birth from central respiratory failure and provide a model for congential central hypoventiliation syndrome. Pbx3 encodes the alternatively spliced Pbx3a and Pbx3b isoform proteins. Pbx3b is the low molecular-weight protein form. It has been localized to various tissues of the central and peripheral nervous systems during mouse embryogenesis (to a lesser extent than Pbx3a). The anti-Pbx3b antibodies could be used in research related to central nervous system and respiratory development.
Applications
