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:

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

FunFam 1052: Uncharacterized protein

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 1 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 Q54WI0 (/IDA)

There are 11 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
Mitotic cytokinesis GO:0000281
A cell cycle process that results in the division of the cytoplasm of a cell after mitosis, resulting in the separation of the original cell into two daughter cells.
1 Q54WI0 (/IMP)
Exocytosis GO:0006887
A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle. Exocytosis can occur either by full fusion, when the vesicle collapses into the plasma membrane, or by a kiss-and-run mechanism that involves the formation of a transient contact, a pore, between a granule (for exemple of chromaffin cells) and the plasma membrane. The latter process most of the time leads to only partial secretion of the granule content. Exocytosis begins with steps that prepare vesicles for fusion with the membrane (tethering and docking) and ends when molecules are secreted from the cell.
1 Q54WI0 (/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 Q54WI0 (/IMP)
Lysosome organization GO:0007040
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a lysosome. A lysosome is a cytoplasmic, membrane-bounded organelle that is found in most animal cells and that contains a variety of hydrolases.
1 Q54WI0 (/IMP)
Lysosomal transport GO:0007041
The directed movement of substances into, out of or within a lysosome.
1 Q54WI0 (/IMP)
Response to bacterium GO:0009617
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 from a bacterium.
1 Q54WI0 (/IMP)
Actin cytoskeleton organization GO:0030036
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins.
1 Q54WI0 (/IMP)
Positive regulation of GTPase activity GO:0043547
Any process that activates or increases the activity of a GTPase.
1 Q54WI0 (/IDA)
Regulation of sporulation GO:0043937
Any process that modulates the frequency, rate or extent of sporulation, the process whose specific outcome is the progression of a spore over time, from its initiation to the mature structure.
1 Q54WI0 (/IGI)
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 Q54WI0 (/IMP)
Regulation of filopodium assembly GO:0051489
Any process that modulates the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.
1 Q54WI0 (/IMP)

GO Term Annotations Evidence
Pericentriolar material GO:0000242
A network of small fibers that surrounds the centrioles in cells; contains the microtubule nucleating activity of the centrosome.
1 Q54WI0 (/IMP)
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 Q54WI0 (/IMP)
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 Q54WI0 (/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 Q54WI0 (/IMP)
Filamentous actin GO:0031941
A two-stranded helical polymer of the protein actin.
