FunFam 4: selenocysteine insertion sequence-binding protein ...

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 10 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
Selenocysteine incorporation GO:0001514
The incorporation of selenocysteine into a peptide; uses a special tRNA that recognizes the UGA codon as selenocysteine, rather than as a termination codon. Selenocysteine is synthesized from serine before its incorporation; it is not a posttranslational modification of peptidyl-cysteine.
2 Q3TGQ4 (/IMP) Q3U1C4 (/IMP)
Striatum development GO:0021756
The progression of the striatum over time from its initial formation until its mature state. The striatum is a region of the forebrain consisting of the caudate nucleus, putamen and fundus striati.
2 Q3TGQ4 (/IMP) Q3U1C4 (/IMP)
Neuron development GO:0048666
The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.
2 Q3TGQ4 (/IMP) Q3U1C4 (/IMP)
Positive regulation of selenocysteine incorporation GO:1904571
Any process that activates or increases the frequency, rate or extent of selenocysteine incorporation.
2 Q3TGQ4 (/ISO) Q3U1C4 (/ISO)
Negative regulation of nuclear-transcribed mRNA catabolic process, nonsense-mediated decay GO:2000623
Any process that stops, prevents or reduces the frequency, rate or extent of nuclear-transcribed mRNA catabolic process, nonsense-mediated decay.
2 Q3TGQ4 (/IMP) Q3U1C4 (/IMP)
Selenocysteine incorporation GO:0001514
The incorporation of selenocysteine into a peptide; uses a special tRNA that recognizes the UGA codon as selenocysteine, rather than as a termination codon. Selenocysteine is synthesized from serine before its incorporation; it is not a posttranslational modification of peptidyl-cysteine.
1 Q9QX72 (/TAS)
Positive regulation of selenocysteine incorporation GO:1904571
Any process that activates or increases the frequency, rate or extent of selenocysteine incorporation.
