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 40: Phosphatidylinositol 3-kinase

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 3 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
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 Q8I3V5 (/IPI)
1-phosphatidylinositol-3-kinase activity GO:0016303
Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol + ATP = a 1-phosphatidyl-1D-myo-inositol 3-phosphate + ADP + 2 H(+).
1 Q8I3V5 (/IDA)
Hemoglobin binding GO:0030492
Interacting selectively and non-covalently with hemoglobin, an oxygen carrying, conjugated protein containing four heme groups and globin.
1 Q8I3V5 (/IDA)

There are 2 GO terms relating to "biological process"

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
Endocytosis GO:0006897
A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle.

Intracellular transport GO:0046907
The directed movement of substances within a cell.
1 Q8I3V5 (/IDA)
