Summary: Peroxisome biogenesis factor 1, N-terminal
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
Peroxisome biogenesis factor 1, N-terminal Provide feedback
Members of this family adopt a double psi beta-barrel fold, similar in structure to the Cdc48 N-terminal domain. It has been suggested that this domain may be involved in interactions with ubiquitin, ubiquitin-like protein modifiers, or ubiquitin-like domains, such as Ubx. Furthermore, the domain may possess a putative adaptor or substrate binding site, allowing for peroxisomal biogenesis, membrane fusion and protein translocation .

Superfamily contains C-terminal domains of N-ethylmaleimide sensitive fusion proteins, VCP-like ATPases, membrane fusion ATPase p97 domain 2, peroxisome biogenesis factor 1 (PEX-1), domain 2, and ubiquitin fusion degradation protein UFD1 families.
The clan contains the following 3 members:CDC48_2 PEX-1N UFD1
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 PEX-1N 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.
