FunFam 27: Gts1p

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 6 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.

There are 7 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
Regulation of transcription by RNA polymerase II GO:0006357
Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II.
2 P40956 (/IPI) P40956 (/IPI)
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.
2 P40956 (/IMP) P40956 (/IMP)
Ultradian rhythm GO:0007624
The specific actions or reactions of an organism that recur with a regularity more frequent than every 24 hours.
2 P40956 (/IMP) P40956 (/IMP)
Negative regulation of phosphatidylinositol biosynthetic process GO:0010512
Any process that decreases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of phosphatidylinositol.
2 P40956 (/IMP) P40956 (/IMP)
Positive regulation of transcription by RNA polymerase II GO:0045944
Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
2 P40956 (/IMP) P40956 (/IMP)
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 Q1ZXH8 (/IMP)
Aggregation involved in sorocarp development GO:0031152
The process whose specific outcome is the progression of the aggregate over time, from its formation to the point when a slug is formed. Aggregate development begins in response to starvation and continues by the chemoattractant-mediated movement of cells toward each other. The aggregate is a multicellular structure that gives rise to the slug.

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
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
2 P40956 (/IDA) P40956 (/IDA)
Cellular bud neck GO:0005935
The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding.
2 P40956 (/HDA) P40956 (/HDA)
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.
2 P40956 (/IDA) P40956 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q1ZXH8 (/IDA)
Cytoskeleton GO:0005856
Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
1 Q1ZXH8 (/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 Q1ZXH8 (/IMP)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 Q1ZXH8 (/IDA)
Early phagosome GO:0032009
A membrane-bounded intracellular vesicle as initially formed upon the ingestion of particulate material by phagocytosis.
