FunFam 277: Actin-binding 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 4 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).
2 P15891 (/IPI) P42522 (/IPI)
Actin filament binding GO:0051015
Interacting selectively and non-covalently with an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.
2 P15891 (/IDA) P42522 (/IDA)
Microtubule binding GO:0008017
Interacting selectively and non-covalently with microtubules, filaments composed of tubulin monomers.
1 P42522 (/IDA)
Myosin light chain binding GO:0032027
Interacting selectively and non-covalently with a light chain of a myosin complex.
1 P42522 (/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
Actin cortical patch assembly GO:0000147
Assembly of an actin cortical patch, a discrete actin-containing structure found at the plasma membrane of fungal cells.
1 P15891 (/IMP)
Pinocytosis GO:0006907
An endocytosis process that results in the uptake of liquid material by cells from their external environment; literally 'cell drinking'. Liquid is enclosed in vesicles, called pinosomes, formed by invagination of the plasma membrane.
1 P42522 (/IGI)
Pinocytosis GO:0006907
An endocytosis process that results in the uptake of liquid material by cells from their external environment; literally 'cell drinking'. Liquid is enclosed in vesicles, called pinosomes, formed by invagination of the plasma membrane.
1 P42522 (/IMP)
Phagocytosis GO:0006909
A vesicle-mediated transport process that results in the engulfment of external particulate material by phagocytes and their delivery to the lysosome. The particles are initially contained within phagocytic vacuoles (phagosomes), which then fuse with primary lysosomes to effect digestion of the particles.
1 P42522 (/IMP)
Mitotic spindle organization GO:0007052
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle.
1 P42522 (/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 P42522 (/IGI)
Protein localization to actin cortical patch GO:0044379
A process in which a protein is transported to, or maintained in, an actin cortical patch.
1 P15891 (/IMP)
Filopodium assembly GO:0046847
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 P42522 (/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 P42522 (/IGI)
Barbed-end actin filament capping GO:0051016
The binding of a protein or protein complex to the barbed (or plus) end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits.
1 P15891 (/IMP)
Positive regulation of Arp2/3 complex-mediated actin nucleation GO:2000601
Any process that activates or increases the frequency, rate or extent of Arp2/3 complex-mediated actin nucleation.
1 P15891 (/IDA)

There are 9 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
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 P15891 (/HDA)
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 P42522 (/IDA)
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 P42522 (/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 P15891 (/IDA)
Actin cortical patch GO:0030479
An endocytic patch that consists of an actin-containing structure found at the plasma membrane in cells; formed of networks of branched actin filaments that lie just beneath the plasma membrane and assemble, move, and disassemble rapidly. An example of this is the actin cortical patch found in Saccharomyces cerevisiae.
