Protein interaction mapping using large-scale two-hybrid analysis has been proposed as a way to functionally annotate large numbers of uncharacterized proteins predicted by complete genome sequences. This approach was examined in Caenorhabditis elegans, starting with 27 proteins involved in vulval development. The resulting map reveals both known and new… (More)
The nucleotide sequence of the yeast DNA plasmid (2 mu circle) from Saccharomyces cerevisiae strain A364A D5 has been determined. The plasmid contains 6,318 base pairs, including two identical inverted repeats of 599 base pairs. Possible functions are suggested, and attributes of an improved vector for cloning foreign DNAs in yeast are discussed.
We describe an in vitro protocol for quickly generating overlapping terminal-labeled restriction fragments for DNA sequence analysis via the Maxam-Gilbert technique. The protocol involves introducing mercurated nucleotides into one end of a region to be sequenced, partial digestion with several restriction enzymes and terminal-labeling, separation of the… (More)
