Solution structure of the inner DysF domain of myoferlin and implications for limb girdle muscular dystrophy type 2b [PDF]
Mutations in the protein dysferlin, a member of the ferlin family, lead to limb girdle muscular dystrophy type 2B and Myoshi myopathy. The ferlins are large proteins characterised by multiple C2 domains and a single C-terminal membrane-spanning helix ...

Lipid binding domains: more than simple lipid effectors
The spatial and temporal regulation of lipid molecules in cell membranes is a hallmark of cellular signaling and membrane trafficking events. Lipid-mediated targeting provides for strict control and versatility, because cell membranes harbor a large ...

Biochemical and functional studies of a novel complement inhibitor, CRIT, with its interaction partners [PDF]
Complement C2 receptor trispanning (CRIT), a three transmembrane receptor, was first discovered on the surface of the parasite Schistosoma haematobium and formerly termed Schistosoma trispanning orphan receptor (Sh-TOR). This receptor acts as decoy C2-

The complement system is one of the first defense lines protecting from invading pathogens. However, it may turn offensive to the body’s own cells and tissues when deregulated by the presence of rare genetic variants that impair physiological regulation ...

μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]
μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

The molecular basis of ceramide-1-phosphate recognition by C2 domains[S]
Group IVA cytosolic phospholipase A2 (cPLA2α), which harbors an N-terminal lipid binding C2 domain and a C-terminal lipase domain, produces arachidonic acid from the sn-2 position of zwitterionic lipids such as phosphatidylcholine. The C2 domain has been

Ferlins and TgDOC2 in Toxoplasma Microneme, Rhoptry and Dense Granule Secretion
The host cell invasion process of apicomplexan parasites like Toxoplasma gondii is facilitated by sequential exocytosis of the microneme, rhoptry and dense granule organelles. Exocytosis is facilitated by a double C2 domain (DOC2) protein family.

Crystal structures of the human Dysferlin inner DysF domain [PDF]
Background: Mutations in dysferlin, the first protein linked with the cell membrane repair mechanism, causes a group of muscular dystrophies called dysferlinopathies.
