Dr Safrany’s interest into inositol phosphates began in 1986, a time when Fison's Pharmaceuticals were looking for InsP3 receptor antagonists. Steve moved to Leicester University Medical School to study inositide signalling at the level of receptor regulation as well as structure-activity relationship studies at the InsP3 receptor, 5-phosphatase and 3-kinase under Stefan Nahorski. In 1994, he moved to NIEHS, NIH, USA to work with Steve Shears and gain biochemical experience. He purified and cloned DIPP - diphosphoinositol polyphosphate phosphohydrolase, the enzyme that metabolises inositol diphosphates (IDPs). He also showed that IDPs are regulated by cell-surface receptors. He returned to the UK (Dundee University) in 1999, having received a Royal Society University Research Fellowship, where he continued these studies. Further appointments at the universities of Bath and Wolverhampton predate his current position as Associate Professor of Pharmacology at RCSI-Bahrain.
