FunFam 42: SON DNA 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 6 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
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).
2 P18583 (/IPI) Q9QX47 (/IPI)
RNA binding GO:0003723
Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
1 P18583 (/HDA)
RNA binding GO:0003723
Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
1 P18583 (/IDA)
RNA binding GO:0003723

1 Q9QX47 (/ISO)
RNA binding GO:0003723
Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
1 Q9QX47 (/ISS)
RS domain binding GO:0050733
Interacting selectively and non-covalently with an RS domain of a protein; RS domains are usually highly phosphorylated and characterized by the presence of arginine (R)/serine (S) dipeptides. The RS domain promotes protein-protein interactions and directs subcellular localization and, in certain situations, nucleocytoplasmic shuttling of individual SR proteins. They also play a role in splicing.
