Phosphoinositide 3-kinase family, accessory domain (PIK domain)
SMART accession number:SM00145
Description: PIK domain is conserved in all PI3 and PI4-kinases. Its role is unclear but it has been suggested to be involved in substrate presentation.
Interpro abstract (IPR001263):

Phosphatidylinositol 3-kinase (PI3K) ( EC ) is an enzyme that phosphorylates phosphoinositides on the 3-hydroxyl group of the inositol ring. The role of the accessory domain of phosphoinositide 3-kinase (PI3-kinase) is unclear. It may be involved in substrate presentation [ (PUBMED:8248783) ].
