26249031 Our data indicated that ITPKA expression was significantly up-regulated in hepatocellular carcinoma and could serve as a potential novel prognostic biomarker
25101901 describe the crystal structure of the complex between human Ca2+/CaM and the CaM-binding region of human IP3-3K isoform A (residues 158-183)
21792881 we conclude that the observed expression of ITPKA early in tumor development increases the metastatic potential of lung adenocarcinoma cells.
20022963 Inositol 1,4,5-trisphosphate 3-kinase-A is a new cell motility-promoting protein that increases the metastatic potential of tumor cells by two functional activities.
18498254 the morphological changes induced by IP3K-A are mediated by non-enzymatic activities of the protein.
18187620 Knockdown of inositol-trisphosphate 3-kinase A (ITPKA) by siRNA inhibits HIV-1 replication in HeLa-derived TZM-bl cells
16525636 Data suggest that ITPKA may be related to carcinogenesis by the modulation of inositol polyphosphates and Ca2+ homeostasis and that ITPKA may be a potential novel molecular target and biomarker.
15350214 We report the structure of an IPK, the human Ins(1,4,5)P3 3-kinase-A, both free and in complexes with substrates and products.
12747803 results highlight the potential role of the three isoforms of InsP3 3-kinase as direct InsP3 metabolizing enzymes and direct regulators of Ca2+ responses to extracellular signals
