The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:
"Cyclin-like
".
FunFam 121: Transcription factor IIIB
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 5 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

TFIIB-class transcription factor binding GO:0001093
Interacting selectively and non-covalently with a general RNA polymerase II transcription factor of the TFIIB class, one of the factors involved in formation of the preinitiation complex (PIC) by RNA polymerase II.

Double-stranded DNA binding GO:0003690
Interacting selectively and non-covalently with double-stranded DNA.
|
1 | O81787 (/IDA) |
|
Protein binding GO:0005515

Transcription, DNA-templated GO:0006351
The cellular synthesis of RNA on a template of DNA.
|
1 | Q387K4 (/ISM) |
|
Transcription by RNA polymerase III GO:0006383
The synthesis of RNA from a DNA template by RNA polymerase III, originating at an RNAP III promoter.
|
1 | Q54U85 (/ISS) |
|
Transcription initiation from RNA polymerase III promoter GO:0006384
Any process involved in the assembly of the RNA polymerase III preinitiation complex (PIC) at an RNA polymerase III promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. Promoter clearance, or release, is the transition between the initiation and elongation phases of transcription.

|
Embryo development ending in seed dormancy GO:0009793
The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.
|
1 | O81787 (/IMP) |
|
Pollen germination GO:0009846
The physiological and developmental changes that occur in a heterosporous plant pollen grain, beginning with hydration and terminating with the emergence of the pollen tube through the aperture.

|
5S class rRNA transcription by RNA polymerase III GO:0042791

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

Transcription factor TFIIIB complex GO:0000126
A transcription factor complex that is involved in regulating transcription from RNA polymerase III (Pol III) promoters. TFIIIB contains the TATA-binding protein (TBP) and two Pol III-specific proteins, B'' and BRF.
