The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

"
Pleckstrin-homology domain (PH domain)/Phosphotyrosine-binding domain (PTB)
".

FunFam 1319: PH and Rap-GAP domain-containing protein DDB_G0271...

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
GTPase activator activity GO:0005096
Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
1 Q55AN8 (/IMP)
Phosphatidylinositol-3,4,5-trisphosphate binding GO:0005547
Interacting selectively and non-covalently with phosphatidylinositol-3,4,5-trisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 3', 4' and 5' positions.
1 Q55AN8 (/IDA)

There are 8 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
Sorocarp development GO:0030587
The process whose specific outcome is the progression of the sorocarp over time, from its formation to the mature structure. The process begins with the aggregation of individual cells and ends with the mature sorocarp. The sorocarp is a structure containing a spore-bearing sorus that sits on top of a stalk. An example of this process is found in Dictyostelium discoideum.
1 Q55AN8 (/IDA)
Sorocarp stalk cell differentiation GO:0031149
The process in which a relatively unspecialized cell acquires specialized features of a sorocarp stalk cell, any of the cellulose-covered cells that form the stalk of a sorocarp. An example of this process is found in Dictyostelium discoideum.
1 Q55AN8 (/IMP)
Negative regulation of GTPase activity GO:0034260
Any process that stops or reduces the rate of GTP hydrolysis by a GTPase.
1 Q55AN8 (/IMP)
Chemotaxis to cAMP GO:0043327
The directed movement of a motile cell or organism in response to the presence of 3',5'-cAMP.
1 Q55AN8 (/IDA)
Cell motility GO:0048870
Any process involved in the controlled self-propelled movement of a cell that results in translocation of the cell from one place to another.
1 Q55AN8 (/IMP)
Regulation of small GTPase mediated signal transduction GO:0051056
Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction.
1 Q55AN8 (/IMP)
Cell-cell adhesion GO:0098609
The attachment of one cell to another cell via adhesion molecules.
1 Q55AN8 (/IMP)
Response to differentiation-inducing factor 1 GO:1903013
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 1-(3,5-dichloro-2,6-dihydroxy-4-methoxyphenyl)hexan-1-one stimulus.
1 Q55AN8 (/HDA)

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.
GO Term Annotations Evidence
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 Q55AN8 (/IDA)
Cell cortex GO:0005938
The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
1 Q55AN8 (/IDA)
Pseudopodium GO:0031143
A temporary protrusion or retractile process of a cell, associated with flowing movements of the protoplasm, and serving for locomotion and feeding.
1 Q55AN8 (/IDA)
Cell leading edge GO:0031252
The area of a motile cell closest to the direction of movement.
1 Q55AN8 (/IDA)
Cell trailing edge GO:0031254
The area of a motile cell opposite to the direction of movement.
1 Q55AN8 (/IDA)
Macropinocytic cup GO:0070685
A cell projection that forms at the site of macropinocytosis, a form of endocytosis that results in the uptake of relatively large amounts of extracellular fluid. The macropinocytic cup membrane selectively excludes certain proteins, such as H36 or PM4C4 in Dictyostelium, and the underlying cytoskeleton is enriched in F-actin and coronin.
