Identification
HMDB Protein ID CDBP04507
Secondary Accession Numbers Not Available
Name Inositol-pentakisphosphate 2-kinase
Description Not Available
Synonyms
  1. IPK1 homolog
  2. Inositol-1,3,4,5,6-pentakisphosphate 2-kinase
  3. Ins(1,3,4,5,6)P5 2-kinase
  4. InsP5 2-kinase
Gene Name IPPK
Protein Type Enzyme
Biological Properties
General Function Involved in ATP binding
Specific 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.
