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.

core domain of the SPFH (stomatin, prohibitin, flotillin, and HflK/C) superfamily; This model summarizes proteins similar to stomatin, prohibitin, flotillin, HflK/C (SPFH) and podocin. The conserved domain common to the SPFH superfamily has also been referred to as the Band 7 domain. Many superfamily members are associated with lipid rafts. Individual proteins of the SPFH superfamily may cluster to form membrane microdomains which may in turn recruit multiprotein complexes. Microdomains formed from flotillin proteins may in addition be dynamic units with their own regulatory functions. Flotillins have been implicated in signal transduction, vesicle trafficking, cytoskeleton rearrangement and are known to interact with a variety of proteins. Stomatin interacts with and regulates members of the degenerin/epithelia Na+ channel family in mechanosensory cells of Caenorhabditis elegans and vertebrate neurons, and participates in trafficking of Glut1 glucose transporters. Prohibitin may act as a chaperone for the stabilization of mitochondrial proteins. Prokaryotic HflK/C plays a role in the decision between lysogenic and lytic cycle growth during lambda phage infection. Flotillins have been implicated 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. Mutations in the podocin gene give rise to autosomal recessive steroid resistant nephritic syndrome.

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.

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
