FunFam 2736: Spindle B

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.

DNA repair GO:0006281
The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.

Double-strand break repair GO:0006302
The repair of double-strand breaks in DNA via homologous and nonhomologous mechanisms to reform a continuous DNA helix.
2 O77135 (/TAS) Q8SZF1 (/TAS)
DNA recombination GO:0006310
Any process in which a new genotype is formed by reassortment of genes resulting in gene combinations different from those that were present in the parents. In eukaryotes genetic recombination can occur by chromosome assortment, intrachromosomal recombination, or nonreciprocal interchromosomal recombination. Interchromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction.
2 O77135 (/ISS) Q8SZF1 (/ISS)
Regulation of translation GO:0006417
Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
2 O77135 (/TAS) Q8SZF1 (/TAS)
Reciprocal meiotic recombination GO:0007131
The cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity.
2 O77135 (/TAS) Q8SZF1 (/TAS)
Germarium-derived oocyte fate determination GO:0007294
The cell fate determination process in which a germarium-derived cell becomes capable of differentiating autonomously into an oocyte cell regardless of its environment; upon determination, the cell fate cannot be reversed. An example of this is found in Drosophila melanogaster.
2 O77135 (/IGI) Q8SZF1 (/IGI)
Intracellular mRNA localization GO:0008298
Any process in which mRNA is transported to, or maintained in, a specific location within the cell.
2 O77135 (/IMP) Q8SZF1 (/IMP)
Intracellular mRNA localization GO:0008298
Any process in which mRNA is transported to, or maintained in, a specific location within the cell.
2 O77135 (/TAS) Q8SZF1 (/TAS)
Polarity specification of anterior/posterior axis GO:0009949
Any process resulting in the establishment of polarity along the anterior/posterior axis.
2 O77135 (/IMP) Q8SZF1 (/IMP)
Polarity specification of dorsal/ventral axis GO:0009951
Any process resulting in the establishment of polarity along the dorsal/ventral axis.
2 O77135 (/IMP) Q8SZF1 (/IMP)
Chromosome condensation GO:0030261
The progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells.
2 O77135 (/TAS) Q8SZF1 (/TAS)
Oocyte karyosome formation GO:0030717
The chromosome organization process in which meiotic chromosomes in the oocyte nucleus cluster together to form a compact spherical structure called the karyosome.
2 O77135 (/IMP) Q8SZF1 (/IMP)
Oogenesis GO:0048477
The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.
2 O77135 (/IGI) Q8SZF1 (/IGI)
Oogenesis GO:0048477
The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.
2 O77135 (/TAS) Q8SZF1 (/TAS)
Double-strand break repair via homologous recombination GO:0000724
The error-free repair of a double-strand break in DNA in which the broken DNA molecule is repaired using homologous sequences. A strand in the broken DNA searches for a homologous region in an intact chromosome to serve as the template for DNA synthesis. The restoration of two intact DNA molecules results in the exchange, reciprocal or nonreciprocal, of genetic material between the intact DNA molecule and the broken DNA molecule.
1 Q9UUL2 (/IGI)
DNA recombinase assembly GO:0000730
The aggregation, arrangement and bonding together of strand exchange proteins (recombinases) into higher order oligomers on single-stranded DNA.
1 Q9UUL2 (/IMP)
Reciprocal meiotic recombination GO:0007131
The cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity.
1 Q9UUL2 (/IMP)
Oocyte fate determination GO:0030716
The process in which a cell becomes capable of differentiating autonomously into an oocyte cell regardless of its environment; upon determination, the cell fate cannot be reversed.
1 O77135 (/IMP)
Strand invasion GO:0042148
The process in which the nucleoprotein complex (composed of the broken single-strand DNA and the recombinase) searches and identifies a region of homology in intact duplex DNA. The broken single-strand DNA displaces the like strand and forms Watson-Crick base pairs with its complement, forming a duplex in which each strand is from one of the two recombining DNA molecules.

A region of a chromosome at which a DNA double-strand break has occurred. DNA damage signaling and repair proteins accumulate at the lesion to respond to the damage and repair the DNA to form a continuous DNA helix.
