Summary: Transcription initiation factor IID, 31kD subunit
Transcription initiation factor IID, 31kD subunit Provide feedback
This family represents the N-terminus of the 31kD subunit (42kD in drosophila) of transcription initiation factor IID (TAFII31). TAFII31 binds to p53, and is an essential requirement for p53 mediated transcription activation.

This tab holds annotation information from the InterPro database.
InterPro entry IPR003162Human transcription initiation factor TFIID is composed of the TATA-binding polypeptide (TBP) and at least 13 TBP-associated factors (TAFs) that collectively or individually are involved in activator-dependent transcription [PUBMED:7667268].
TAFII-31 protein is a transcriptional coactivator of the p53 protein [PUBMED:7761466].

Members of this clan all possess a histone fold. Generally proteins in this clan are DNA binding.
The clan contains the following 11 members:Bromo_TP CBFD_NFYB_HMF CENP-S CENP-T CENP-W Histone TAF TAFII28 TFIID-18kDa TFIID-31kDa TFIID_20kDa
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the TFIID-31kDa domain has been found. There are 1 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
