The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:
"Helix-loop-helix DNA-binding domain
".
FunFam 5338: Class E basic helix-loop-helix protein 40
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 30 GO terms relating to "molecular function"
