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.

GO Term Annotations Evidence
Positive regulation of response to DNA damage stimulus GO:2001022
Any process that activates or increases the frequency, rate or extent of response to DNA damage stimulus.
8 Q3T0X7 (/ISS) Q499U6 (/ISS) Q5RAZ5 (/ISS) Q6DGT7 (/ISS) Q6P881 (/ISS) Q6PAF4 (/ISS) Q6PAF4 (/ISS) Q9D720 (/ISS)
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 Q53EK2 (/IMP)
Meiosis I GO:0007127
The first meiotic nuclear division in which homologous chromosomes are paired and segregated from each other, producing two haploid daughter nuclei.
1 Q53EK2 (/IMP)
Response to UV GO:0009411
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an ultraviolet radiation (UV light) stimulus. Ultraviolet radiation is electromagnetic radiation with a wavelength in the range of 10 to 380 nanometers.
1 Q54X37 (/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 Q54X37 (/IMP)
Protein modification by small protein conjugation or removal GO:0070647
A protein modification process in which one or more groups of a small protein, such as ubiquitin or a ubiquitin-like protein, are covalently attached to or removed from a target protein.

Positive regulation of response to DNA damage stimulus GO:2001022
Any process that activates or increases the frequency, rate or extent of response to DNA damage stimulus.

Smc5-Smc6 complex GO:0030915
A conserved complex that contains a heterodimer of SMC proteins (Smc5p and Smc6p, or homologs thereof) and several other proteins, and is involved in DNA repair and maintaining cell cycle arrest following DNA damage. In S. cerevisiae, this is an octameric complex called Mms21-Smc5-Smc6 complex, with at least five of its subunits conserved in fission yeast and humans.
