... by performing co-immunoprecipitation experiments. We unexpectedly discovered that TMEM266 proteins natively interact with the novel short form splice variants that only have voltage-sensor domains and putative cytosolic coiled-coil region in cerebellum. The crystal structure of coiled-coil region of TMEM266...

...Nicholas J. Schill; Richard A. Anderson The generation of various phosphoinositide messenger molecules at distinct locations within the cell is mediated via the specific targeting of different isoforms and splice variants of phosphoinositide kinases. The lipid messenger PtdIns(4,5) P 2 is generated...

... cyclohydrolase I; EC 3.5.4.16). In previous work, catalytically inactive human GCH splice variants differing from the wild-type enzyme within the last 20 C-terminal amino acids were identified. In the present study, we searched for a possible role of these splice variants. Gel filtration profiles of purified...

... yielding rAbca5 fused either to EGFP (enhanced green fluorescent protein) or to a peptide bearing the viral V5 epitope. During rAbca5 cDNA cloning, we discovered a splice variant sequence (rAbca5 V20+16), predicted to give rise to a truncated, half-size transporter, which was highly homologous with a human...

... in blood-derived cell lines (CEM, THP-1 and Jurkat), with a novel variant, not identified in the EST database, found in CEM cells only. The major splice variant increased gene expression 9–11-fold in a luciferase reporter assay, while the other isoforms were similar or slightly greater than the control. We...

... signalling appears to be involved in short- and long-term events such as neurotransmission, secretion, cell growth, proliferation and death [ 6 ]. C-terminus ecto-ATPase ecto-nucleoside triphosphate diphosphohydrolase-2 (NTPDase2, CD39L1) protein kinase splice variant NTPDase activity...

...Claus SCHNEIDER; William E. BOEGLIN; Alan R. BRASH The two COX (cyclo-oxygenase) isoenzymes COX-1 and -2 catalyse the initial step in the conversion of arachidonic acid into PG (prostaglandin) hormones. The identification of an mRNA transcript encoding a splice variant of human COX-1 was reported...

...Maria-Luisa GIUDICI; Piers C. EMSON; Robin F. IRVINE Type I PIPkins (phosphatidylinositol 4-phosphate 5-kinases) are the enzymes that catalyse the major cellular route of synthesis of PtdIns(4,5) P 2 , and three isoforms (α, β and γ) with several splice variants have been found to date...
