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, accessory domain (PIK)
".

FunFam 5: Phosphatidylinositol 4-phosphate 3-kinase C2 domai...

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).
3 E9QAN8 (/IPI) O00750 (/IPI) O00750 (/IPI)
1-phosphatidylinositol-4-phosphate 3-kinase activity GO:0035005
Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol 4-phosphate + ATP = 1-phosphatidyl-1D-myo-inositol 3,4-bisphosphate + ADP + 2 H(+).
2 O00750 (/NAS) O00750 (/NAS)
Lipid kinase activity GO:0001727
Catalysis of the phosphorylation of a simple or complex lipid.
1 E9QAN8 (/IDA)

There are 6 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
Phosphatidylinositol biosynthetic process GO:0006661
The chemical reactions and pathways resulting in the formation of phosphatidylinositol, any glycophospholipid in which the sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.
2 O00750 (/TAS) O00750 (/TAS)
Cellular response to starvation GO:0009267
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.
1 E9QAN8 (/IGI)
Macroautophagy GO:0016236
The major inducible pathway for the general turnover of cytoplasmic constituents in eukaryotic cells, it is also responsible for the degradation of active cytoplasmic enzymes and organelles during nutrient starvation. Macroautophagy involves the formation of double-membrane-bounded autophagosomes which enclose the cytoplasmic constituent targeted for degradation in a membrane-bounded structure. Autophagosomes then fuse with a lysosome (or vacuole) releasing single-membrane-bounded autophagic bodies that are then degraded within the lysosome (or vacuole). Some types of macroautophagy, e.g. pexophagy, mitophagy, involve selective targeting of the targets to be degraded.
1 E9QAN8 (/IGI)
Phosphatidylinositol-3-phosphate biosynthetic process GO:0036092
The chemical reactions and pathways resulting in the formation of phosphatidylinositol-3-phosphate, a phosphatidylinositol monophosphate carrying the phosphate group at the 3-position.
1 E9QAN8 (/IGI)
Protein kinase B signaling GO:0043491
A series of reactions, mediated by the intracellular serine/threonine kinase protein kinase B (also called AKT), which occurs as a result of a single trigger reaction or compound.
1 E9QAN8 (/IDA)
Autophagosome organization GO:1905037
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an autophagosome.
1 E9QAN8 (/IGI)

There are 6 GO terms relating to "cellular component"

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.

Cytosol GO:0005829

That part of the nuclear content other than the chromosomes or the nucleolus.
1 E9QAN8 (/ISO)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 E9QAN8 (/ISO)
Endocytic vesicle GO:0030139
A membrane-bounded intracellular vesicle formed by invagination of the plasma membrane around an extracellular substance. Endocytic vesicles fuse with early endosomes to deliver the cargo for further sorting.
