Family: PRELI (PF04707)

Summary: PRELI-like family

Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.

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.

This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.

PRELI-like family Provide feedback

This family includes a conserved region found in the PRELI protein and yeast YLR168C gene MSF1 product. The function of this protein is unknown, though it is thought to be involved in intra-mitochondrial protein sorting. This region is also found in a number of other eukaryotic proteins.

This tab holds annotation information from the InterPro database.

InterPro entry IPR006797

The PRELI/MSF1 domain is an eukaryotic protein module which occurs in stand- alone form in several proteins, including the human PRELI protein and the yeast MSF1 protein, and as an amino-terminal domain in an orthologous group of proteins typified by human SEC14L1, which is conserved in all animals. In this group of proteins, the PRELI/MSF1 domain co-occurs with the CRAL-TRIO and the GOLD domains. The PRELI/MSF1 domain is approximately 170 residues long and is predicted to assume a globular alpha + beta fold with six beta strands and four alpha helices. It has been suggested that the PRELI/MSF1 domain may have a function associated with cellular membrane [PUBMED:12049664].

Pfam Clan

This family is a member of clan Bet_V_1_like (CL0209), which has the following description:

The Bet_V_I family is composed of sequences related to the major Birch (Betula verrucose) pollen antigen Betv1. This allergen is known to cause hayfever, dermatitis, asthma and occasionally anaphylactic shock. The other families in this clan share the same structure as Betv1 which is composed of antiparallel beta sheets and alpha helices. There is a cavity between the beta sheet and a long C terminal helix. The cavity appears to play roles in the binding of lipid molecules [1][2][3] which seems a common feature of the families in this clan.

The clan contains the following 17 members:

Alignments

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the UniProtKB sequence database, the NCBI sequence database, and our metagenomics sequence database. More...

View options

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...

Trees

This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.

Note: You can also download the data file for the tree.

Structures

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 PRELI domain has been found. There are 18 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.
