FunFam 19672: Related to budding protein BOI2

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
Transcription factor activity, sequence-specific DNA binding GO:0003700
Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
1 O60861 (/TAS)
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).
1 O60861 (/IPI)
Phospholipid binding GO:0005543
Interacting selectively and non-covalently with phospholipids, a class of lipids containing phosphoric acid as a mono- or diester.
1 G4MV02 (/ISS)

There are 5 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
Cell cycle arrest GO:0007050
A regulatory process that halts progression through the cell cycle during one of the normal phases (G1, S, G2, M).
1 O60861 (/TAS)
Rho protein signal transduction GO:0007266
A series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state.
1 G4MV02 (/ISS)
Regulation of cell shape GO:0008360
Any process that modulates the surface configuration of a cell.
1 O74653 (/IMP)
Regulation of exocytosis GO:0017157
Any process that modulates the frequency, rate or extent of exocytosis.
1 O74653 (/IGI)
Establishment of cell polarity GO:0030010
The specification and formation of anisotropic intracellular organization or cell growth patterns.
1 G4MV02 (/ISS)

There are 7 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
Cellular bud GO:0005933
A protuberance from a cell of an organism that reproduces by budding, which will grow larger and become a separate daughter cell after nuclear division, cytokinesis, and cell wall formation (when appropriate). The daughter cell may completely separate from the mother cell, or the mother and daughter cells may remain associated.
1 G4MV02 (/ISS)
Cellular bud neck GO:0005935
The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding.
1 G4MV02 (/ISS)
Site of polarized growth GO:0030427
Any part of a cell where non-isotropic growth takes place.
1 G4MV02 (/ISS)
Medial cortex GO:0031097
A medial cortical band overlaying the nucleus which acts as a landmark for contractile ring positioning and plays a role in cell cycle regulation.
1 O74653 (/IDA)
Cell division site GO:0032153
The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.
1 O74653 (/IDA)
Cell cortex of cell tip GO:0051285
The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.
1 O74653 (/IDA)
Cell tip GO:0051286
The region at the end of the longest axis of a cylindrical or elongated cell.
