The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Helix-loop-helix DNA-binding domain
".
FunFam 45: upstream stimulatory factor 2 isoform X1
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 24 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.
