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:

"
Smaug, PHAT domain

FunFam 5: Smg, isoform B

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 8 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
Translation repressor activity GO:0030371
Antagonizes ribosome-mediated translation of mRNA into a polypeptide.
5 B3NFQ7 (/ISS) B4HKJ7 (/ISS) B4QMP1 (/ISS) B4QMP1 (/ISS) P60320 (/ISS)
Translation repressor activity, mRNA regulatory element binding GO:0000900
Antagonizes the ribosome-mediated translation of mRNA into a polypeptide via direct binding (through a selective and non-covalent interaction) to nucleic acid.
1 Q23972 (/TAS)
MRNA binding GO:0003729
Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.
1 Q23972 (/TAS)
MRNA 3'-UTR binding GO:0003730
Interacting selectively and non-covalently with the 3' untranslated region of an mRNA molecule.
1 Q23972 (/TAS)
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 Q23972 (/IPI)
Myosin binding GO:0017022
Interacting selectively and non-covalently with any part of a myosin complex; myosins are any of a superfamily of molecular motor proteins that bind to actin and use the energy of ATP hydrolysis to generate force and movement along actin filaments.
1 Q23972 (/IPI)
Translation repressor activity GO:0030371
Antagonizes ribosome-mediated translation of mRNA into a polypeptide.
1 Q23972 (/IDA)
Translation repressor activity GO:0030371
Antagonizes ribosome-mediated translation of mRNA into a polypeptide.

There are 7 GO terms relating to "biological process"

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
Negative regulation of translation GO:0017148
Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
5 B3NFQ7 (/ISS) B4HKJ7 (/ISS) B4QMP1 (/ISS) B4QMP1 (/ISS) P60320 (/ISS)
Nuclear-transcribed mRNA poly(A) tail shortening GO:0000289
Shortening of the poly(A) tail of a nuclear-transcribed mRNA from full length to an oligo(A) length.
1 Q23972 (/IMP)
Negative regulation of translation GO:0017148
Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
1 Q23972 (/IDA)
Negative regulation of translation GO:0017148
Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
1 Q23972 (/TAS)
Regulation of mRNA stability GO:0043488
Any process that modulates the propensity of mRNA molecules to degradation. Includes processes that both stabilize and destabilize mRNAs.
1 Q23972 (/IMP)
Establishment of RNA localization GO:0051236
The directed movement of RNA to a specific location.
1 Q23972 (/IMP)
Positive regulation of nuclear-transcribed mRNA poly(A) tail shortening GO:0060213
Any process that increases the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.

There are 3 GO terms relating to "cellular component"

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
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
5 B3NFQ7 (/ISS) B4HKJ7 (/ISS) B4QMP1 (/ISS) B4QMP1 (/ISS) P60320 (/ISS)
P-body GO:0000932
A focus in the cytoplasm where mRNAs may become inactivated by decapping or some other mechanism. Protein and RNA localized to these foci are involved in mRNA degradation, nonsense-mediated mRNA decay (NMD), translational repression, and RNA-mediated gene silencing.
