A proteomics method has been developed to purify and identify the specific proteins modified by ubiquitin (Ub) from human cells. In purified samples, Ub and 21 other proteins were identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) spectra using SEQUEST. These proteins included several of the expected carriers of Ub including(More)
A family of growth hormone releasing peptides have been isolated and characterized from human pancreatic islet cell tumours. We have compared the growth hormone release in normal volunteers and patients with various hypothalamo-pituitary disorders, following direct stimulation of the pituitary using 50 micrograms of the most potent homologue, hp GRF 1-44(More)
