Comments

Comment Type Description
Catalytic Activity ATP + 1-phosphatidyl-1D-myo-inositol = ADP + 1-phosphatidyl-1D-myo-inositol 4-phosphate.
Function Acts on phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol 1,4,5,- trisphosphate. PIK1 is part of a nuclear phosphoinositide cycle and could control cytokinesis through the actin cytoskeleton.
Interaction Q06389:FRQ1; NbExp=3; IntAct=EBI-13423, EBI-11946;
Miscellaneous Present with 1600 molecules/cell in log phase SD medium. {ECO:0000269|PubMed:14562106}.
Similarity Belongs to the PI3/PI4-kinase family. Type III PI4K subfamily. {ECO:0000305}.
Similarity Contains 1 PI3K/PI4K domain. {ECO:0000255|PROSITE- ProRule:PRU00269}.
Similarity Contains 1 PIK helical domain. {ECO:0000255|PROSITE- ProRule:PRU00878}.
Subcellular Location Nucleus.
Subunit Interacts with FRQ1. {ECO:0000269|PubMed:10559922}.
