FunFam 184: Protein kinase activator Bem1

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
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 P40996 (/IPI)
Protein binding, bridging GO:0030674
The binding activity of a molecule that brings together two or more protein molecules, or a protein and another macromolecule or complex, through a selective, non-covalent, often stoichiometric interaction, permitting those molecules to function in a coordinated way.
1 P40996 (/IPI)
Phosphatidylinositol binding GO:0035091
Interacting selectively and non-covalently with any inositol-containing glycerophospholipid, i.e. phosphatidylinositol (PtdIns) and its phosphorylated derivatives.
1 P40996 (/ISM)

There are 8 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
Sporocarp development involved in asexual reproduction GO:0000905
The formation of a spore-bearing structure by fungus where spores will arise from asexual reproduction.
2 Q5AXF0 (/IMP) Q5AXF0 (/IMP)
Vacuole organization GO:0007033
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a vacuole.
2 Q5AXF0 (/IMP) Q5AXF0 (/IMP)
Spore germination GO:0009847
The physiological and developmental changes that occur in a spore following release from dormancy up to the earliest signs of growth (e.g. emergence from a spore wall).
2 Q5AXF0 (/IMP) Q5AXF0 (/IMP)
Conjugation with cellular fusion GO:0000747
A conjugation process that results in the union of cellular and genetic information from compatible mating types. An example of this process is found in Saccharomyces cerevisiae.
1 P40996 (/IMP)
Cell morphogenesis involved in conjugation with cellular fusion GO:0000753
The change in form (cell shape and size) that occurs during sexual reproduction in order to facilitate direct contact between the compatible mating types in organisms that undergo conjugation cellular fusion.
1 P40996 (/IMP)
Cdc42 protein signal transduction GO:0032488
A series of molecular signals within the cell that are mediated by the Cdc42 protein switching to a GTP-bound active state.
1 P40996 (/TAS)
Establishment or maintenance of cell polarity regulating cell shape GO:0071963
Any cellular process that results in the specification, formation or maintenance of a polarized intracellular organization or cell growth patterns that regulate the shape of a cell.
1 P40996 (/IMP)
Regulation of establishment or maintenance of cell polarity regulating cell shape GO:2000769
Any process that modulates the frequency, rate or extent of establishment or maintenance of cell polarity regulating cell shape.

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
Hyphal tip polarisome GO:0031562
Protein complex that has a role in determining cell polarity, found at the tip of a growing fungal hypha.
2 Q5AXF0 (/IDA) Q5AXF0 (/IDA)
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.
1 P40996 (/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 P40996 (/HDA)
Plasma membrane of cell tip GO:0031520
The portion of the plasma membrane surrounding the cell tip.
1 P40996 (/EXP)
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 P40996 (/HDA)
Mating projection tip GO:0043332
The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.
1 P40996 (/IDA)
Cell tip GO:0051286
The region at the end of the longest axis of a cylindrical or elongated cell.
1 P40996 (/HDA)
Cdc42 GTPase complex GO:0071521
A protein complex formed by the association of the small GTPase Cdc42 with additional proteins. In Schizosaccharomyces the complex contains the Cdc42, Ras1, Scd1, Scd2, andShk1 proteins, and functions in the Ras1-Scd GTPase signalling pathway.
1 P40996 (/TAS)
Cortical dynamic polarity patch GO:0090726
A region of the cell cortex that contains a higher concentration of growth polarity factors than the surrounding cortex and that changes position over time. An example is found in fission yeast cells during early mating, in which the GTPase Cdc42 dynamically to discrete zones within the cortex prior to shmoo formation.
