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 394: Homologous-pairing protein 2 homolog

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 17 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.

Estrogen receptor binding GO:0030331
Interacting selectively and non-covalently with an estrogen receptor.
2 O35047 (/ISO) O35047 (/ISO)
Nuclear receptor transcription coactivator activity GO:0030374
The function of a transcription cofactor that activates transcription in conjuction with a ligand-dependent nuclear receptor from a RNA polymerase II promoter; does not bind DNA itself.
2 Q9P2W1 (/IMP) Q9P2W1 (/IMP)
Nuclear receptor transcription coactivator activity GO:0030374
The function of a transcription cofactor that activates transcription in conjuction with a ligand-dependent nuclear receptor from a RNA polymerase II promoter; does not bind DNA itself.

2 O35047 (/ISO) O35047 (/ISO)
Protein homodimerization activity GO:0042803
Interacting selectively and non-covalently with an identical protein to form a homodimer.
2 O35047 (/ISO) O35047 (/ISO)
Thyroid hormone receptor binding GO:0046966
Interacting selectively and non-covalently with a thyroid hormone receptor.
2 O35047 (/ISO) O35047 (/ISO)
Androgen receptor binding GO:0050681
Interacting selectively and non-covalently with an androgen receptor.
2 O35047 (/ISO) O35047 (/ISO)
DBD domain binding GO:0050692
Interacting selectively and non-covalently with the DBD, DNA binding domain, of a protein. The DNA binding domain of the vitamin D receptor, one of a family of receptors with the DBD, is split into three regions, the P, D and T boxes. Residues that are critical for target sequence selectivity form the P-box. The D-box contains residues that are important for homodimerization of class I nuclear receptors. The T-box is essential for both DNA-binding and transactivation of the VDR; this region may also be important for dimerization with RXR for class II nuclear receptors.
2 O35047 (/ISO) O35047 (/ISO)
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).

Interacting selectively and non-covalently with an estrogen receptor.
1 Q91ZY6 (/IDA)
