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:

"
Winged helix-like DNA-binding domain superfamily/Winged helix DNA-binding domain

FunFam 232: lysine-specific histone demethylase 1B

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.
GO Term Annotations Evidence
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
2 Q8CIG3 (/IDA) Q8NB78 (/IDA)
Histone demethylase activity (H3-dimethyl-K4 specific) GO:0034648
Catalysis of the removal of a methyl group from dimethylated lysine at position 4 of the histone H3 protein.
2 Q8CIG3 (/IDA) Q8NB78 (/IDA)
Histone demethylase activity (H3-monomethyl-K4 specific) GO:0034649
Catalysis of the reaction: histone H3 N6-methyl-L-lysine (position 4) + O2 + FAD + H2O = histone H3 L-lysine (position 4) + H2O2 + formaldehyde + FADH2. This reaction is the removal of a methyl group from monomethylated lysine at position 4 of the histone H3 protein.
2 Q8CIG3 (/IDA) Q8NB78 (/IDA)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 Q8NB78 (/IPI)
Histone demethylase activity (H3-dimethyl-K4 specific) GO:0034648
Catalysis of the removal of a methyl group from dimethylated lysine at position 4 of the histone H3 protein.
1 Q8NB78 (/ISS)
Histone demethylase activity (H3-monomethyl-K4 specific) GO:0034649
Catalysis of the reaction: histone H3 N6-methyl-L-lysine (position 4) + O2 + FAD + H2O = histone H3 L-lysine (position 4) + H2O2 + formaldehyde + FADH2. This reaction is the removal of a methyl group from monomethylated lysine at position 4 of the histone H3 protein.
1 Q8NB78 (/ISS)
Histone binding GO:0042393
Interacting selectively and non-covalently with a histone, any of a group of water-soluble proteins found in association with the DNA of eukaroytic chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity.
1 Q8NB78 (/IDA)
Flavin adenine dinucleotide binding GO:0050660
Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
1 Q8CIG3 (/IDA)
FAD binding GO:0071949
Interacting selectively and non-covalently with the oxidized form, FAD, of flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes.
1 Q8NB78 (/IDA)
FAD binding GO:0071949
Interacting selectively and non-covalently with the oxidized form, FAD, of flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes.
