FunFam 23: Rho GTPase-activating 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 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
MRNA binding GO:0003729
Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.
2 P39960 (/HDA) P39960 (/HDA)
GTPase activator activity GO:0005096
Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
2 P39960 (/IDA) P39960 (/IDA)
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 P39960 (/IPI) P39960 (/IPI)

There are 3 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 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.
2 P39960 (/IMP) P39960 (/IMP)
Negative regulation of Rho protein signal transduction GO:0035024
Any process that stops, prevents, or reduces the frequency, rate or extent of Rho protein signal transduction.
2 P39960 (/IGI) P39960 (/IGI)
Negative regulation of Rho protein signal transduction GO:0035024
Any process that stops, prevents, or reduces the frequency, rate or extent of Rho protein signal transduction.
2 P39960 (/IMP) P39960 (/IMP)

There are 8 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
Incipient cellular bud site GO:0000131
The portion of the budding yeast plasma membrane where a daughter cell will emerge. The yeast marks this spot with bud-site selection proteins before bud emergence occurs. Actin is polarized to this spot just prior to and during bud emergence.
2 P39960 (/IDA) P39960 (/IDA)
Prospore membrane GO:0005628
The prospore membrane is a double-membraned structure that extends from the cytoplasmic face of the spindle pole bodies to encompass the spindle pole bodies and the four nuclear lobes that are formed during meiosis. It helps isolate the meiotic nuclei from the cytoplasm during spore formation and serves as a foundation for the formation of the spore walls. An example of this component is found in Schizosaccharomyces pombe.
2 P39960 (/HDA) P39960 (/HDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
2 P39960 (/IDA) P39960 (/IDA)
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
2 P39960 (/HDA) P39960 (/HDA)
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.
2 P39960 (/IDA) P39960 (/IDA)
Cellular bud tip GO:0005934
The end of a cellular bud distal to the site of attachment to the mother cell.
2 P39960 (/IDA) P39960 (/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.
2 P39960 (/IDA) P39960 (/IDA)
Mating projection tip GO:0043332
The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.
