Divecha N, et al.  (1995) The cloning and sequence of the C isoform of PtdIns4P 5-kinase. Biochem J 309 ( Pt 3)():715-9

Abstract: In this study we describe the purification and sequencing of the C isoform of platelet PtdIns4P 5-kinase. Subsequently a cDNA was isolated from a human circulating-leucocyte library, which when sequenced was shown to contain all of the peptides identified in the purified protein. In addition, expression of this cDNA in bacteria led to the production of a protein which was recognized by specific monoclonal antibodies raised to the bovine brain enzyme [Brooksbank, Hutchings, Butcher, Irvine and Divecha (1993) Biochem. J. 291, 77-82] and also led to the appearance of PtdIns4P 5-kinase activity in the bacterial lysates. Interestingly, the cDNA showed no similarity to any of the previously cloned inositide kinases. A search of the DNA databases showed that two proteins from Saccharomyces cerevisiae shared close similarity to this enzyme, one of which, the mss4 gene product, has been implicated in the yeast inositol lipid pathway. These data suggest that the PtdIns4P 5-kinases are a new family of inositide kinases unrelated to the previously cloned phosphoinositide 3/4-kinases.
