We developed a new DNA microarray-based technology, called protein binding microarrays (PBMs), that allows rapid, high-throughput characterization of the in vitro DNA binding-site sequence specificities of transcription factors in a single day. Using PBMs, we identified the DNA binding-site sequence specificities of the yeast transcription factors Abf1,(More)
Apolipoprotein E (apoE) and certain peptides derived from it have been shown to exert neurotoxic effects in vitro, and apoE has been linked to the etiology of Alzheimer's disease. The mechanisms underlying these toxic and pathological effects are, however, not known. To approach this question, we have studied the effects of apoE peptides on the cytoplasmic(More)
We identified relaxin in human male prostate by use of an anti-human relaxin analogue polyclonal antibody and the avidin-biotin-immunoperoxidase method. The antibody was obtained by immunizing a rabbit with a synthetic human relaxin analogue which has 95% sequence homology with native human relaxin. Human prostate tissues incubated with the anti-human(More)
Mammalian cells express several distinct isoforms of transcription factor CREB (cAMP-responsive element binding protein). At least two forms, alpha- and delta CREB, arise through alternative splicing of the CREB gene transcript. In this communication we demonstrate that the mRNAs of several CREB isoforms are expressed in rat C6 glioma cells and that the(More)
