Flotillin or reggie family; SPFH (stomatin, prohibitin, flotillin, and HflK/C) superfamily; The flotillin (reggie) like proteins are lipid raft-associated. Individual proteins of this SPFH family may cluster to form membrane microdomains which may in turn recruit multiprotein complexes. In addition, microdomains formed from flotillin proteins may be dynamic units with their own regulatory functions. Flotillins have been implicated in signal transduction, vesicle trafficking, cytoskeleton rearrangement and interact with a variety of proteins. They may play a role in the progression of prion disease, in the pathogenesis of neurodegenerative diseases such as Parkinson's and Alzheimer's disease and in cancer invasion, and metastasis.

Flotillin; Flotillin is a family of lipid-membrane-associated proteins found in bacteria, archaea and eukaryotes. The family is found in association with pfam01145, another integral membrane-associated domain. Flotillins in vertebrates are associated with sphingolipids and cholesterol-enriched membrane microdomains known as lipid-rafts. These rafts along with other membrane components are important in cell-signalling. Flotillins in other organizms have roles in viral pathogenesis, endocytosis, and membrane shaping.

High frequency of lysogenization K (HflK) family; SPFH (stomatin, prohibitin, flotillin, and HflK/C) superfamily; This model characterizes proteins similar to prokaryotic HflK (High frequency of lysogenization K). Although many members of the SPFH (or band 7) superfamily are lipid raft associated, prokaryote plasma membranes lack cholesterol and are unlikely to have lipid raft domains. Individual proteins of this SPFH domain superfamily may cluster to form membrane microdomains which may in turn recruit multiprotein complexes. Escherichia coli HflK is an integral membrane protein which may localize to the plasma membrane. HflK associates with another SPFH superfamily member (HflC) to form an HflKC complex. HflKC interacts with FtsH in a large complex termed the FtsH holo-enzyme. FtsH is an AAA ATP-dependent protease which exerts progressive proteolysis against membrane-embedded and soluble substrate proteins. HflKC can modulate the activity of FtsH. HflKC plays a role in the decision between lysogenic and lytic cycle growth during lambda phage infection.

of the residues that compose this conserved feature have been mapped to the query sequence.
Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
