The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Phosphatidylinositol 3-kinase Catalytic Subunit; Chain A, domain 4
".

FunFam 12: Phosphatidylinositol 4-kinase alpha 1

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
1-phosphatidylinositol 4-kinase activity GO:0004430
Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol + ATP = 1-phosphatidyl-1D-myo-inositol 4-phosphate + ADP + 2 H(+).
1 Q9SXA1 (/IDA)
Phosphatidylinositol-4,5-bisphosphate binding GO:0005546
Interacting selectively and non-covalently with phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions.
1 Q9SXA1 (/IDA)
Actin filament binding GO:0051015

1 Q9SXA1 (/IDA)
Phosphatidylinositol-4-phosphate binding GO:0070273
Interacting selectively and non-covalently with phosphatidylinositol-4-phosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' position.
1 Q9SXA1 (/IDA)
Phosphatidic acid binding GO:0070300
