FunFam 14: Phosphatidylinositol 3-kinase, root isoform

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 2 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 P42339 (/IPI)
1-phosphatidylinositol-3-kinase activity GO:0016303

There are 19 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
Reproduction GO:0000003
The production of new individuals that contain some portion of genetic material inherited from one or more parent organisms.
1 Q9TXI7 (/IMP)
Nematode larval development GO:0002119
The process whose specific outcome is the progression of the nematode larva over time, from its formation to the mature structure. Nematode larval development begins with the newly hatched first-stage larva (L1) and ends with the end of the last larval stage (for example the fourth larval stage (L4) in C. elegans). Each stage of nematode larval development is characterized by proliferation of specific cell lineages and an increase in body size without alteration of the basic body plan. Nematode larval stages are separated by molts in which each stage-specific exoskeleton, or cuticle, is shed and replaced anew.
1 Q9TXI7 (/IMP)
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.
1 P42339 (/IDA)
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.
1 P42339 (/IMP)
Nuclear envelope organization GO:0006998
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nuclear envelope.
1 Q9TXI7 (/IMP)
Determination of adult lifespan GO:0008340
The control of viability and duration in the adult phase of the life-cycle.
1 Q9TXI7 (/IGI)
Response to salt stress GO:0009651
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.
1 P42339 (/IMP)
Regulation of endocytosis GO:0030100
Any process that modulates the frequency, rate or extent of endocytosis.
1 Q9TXI7 (/IMP)
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 Q9TXI7 (/IMP)
Ecdysis, collagen and cuticulin-based cuticle GO:0042395
The shedding of the old collagen and cuticulin-based cuticle fragments during the molting cycle. Examples of this process are found in invertebrates.
1 Q9TXI7 (/IMP)
Regulation of protein secretion GO:0050708
Any process that modulates the frequency, rate or extent of the controlled release of a protein from a cell.
1 Q9TXI7 (/IMP)
Regulation of endosome size GO:0051036
Any process that modulates the volume of an endosome, a membrane-bounded organelle that carries materials newly ingested by endocytosis.
1 Q9TXI7 (/IGI)
Microgametogenesis GO:0055046
The process whose specific outcome is the progression of the pollen grain over time, from its formation as the microspore to the mature structure.

Positive regulation of triglyceride lipase activity GO:0061365
Any process that increases the activity of triglyceride lipase.
1 Q9TXI7 (/IMP)
Reactive oxygen species metabolic process GO:0072593
The chemical reactions and pathways involving a reactive oxygen species, any molecules or ions formed by the incomplete one-electron reduction of oxygen. They contribute to the microbicidal activity of phagocytes, regulation of signal transduction and gene expression, and the oxidative damage to biopolymers.
1 P42339 (/IMP)
Phagosome maturation involved in apoptotic cell clearance GO:0090386
A process that is carried out at the cellular level which results in the arrangement of constituent parts of a phagosome within a cell and contributes to apoptotic cell clearance. Phagosome maturation begins with endocytosis and formation of the early phagosome and ends with the formation of the hybrid organelle, the phagolysosome.
1 Q9TXI7 (/IGI)
Phagosome maturation involved in apoptotic cell clearance GO:0090386
A process that is carried out at the cellular level which results in the arrangement of constituent parts of a phagosome within a cell and contributes to apoptotic cell clearance. Phagosome maturation begins with endocytosis and formation of the early phagosome and ends with the formation of the hybrid organelle, the phagolysosome.

GO Term Annotations Evidence
Nuclear outer membrane GO:0005640
The outer, i.e. cytoplasm-facing, lipid bilayer of the nuclear envelope; continuous with the endoplasmic reticulum of the cell and sometimes studded with ribosomes.
1 Q9TXI7 (/IDA)
Nucleolus GO:0005730
A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.
1 Q9TXI7 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
