Protein Structure
UniProt Annotation
Function Phosphorylates Ins(1,3,4,5,6)P5 at position 2 to form Ins(1,2,3,4,5,6)P6 (InsP6 or phytate). InsP6 is involved in many processes such as mRNA export, non-homologous end-joining, endocytosis, ion channel regulation. It also protects cells from TNF-alpha-induced apoptosis. {ECO:0000269PubMed:12084730, ECO:0000269PubMed:15967797}.
Subcellular Localization Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
Disease Associations
Tissue Specificity Ubiquitously expressed, with high expression in heart, brain, testis and placenta. {ECO:0000269PubMed:12084730}.
