Domain Architecture (Details)
InterPro domains unassigned to SynO:
Many calcium-binding proteins belong to the same evolutionary family and share a type of calcium-binding domain known as the EF-hand. This type of domain consists of a twelve residue loop flanked on both side by a twelve residue alpha-helical domain. In an EF-hand loop the calcium ion is coordinated in a pentagonal bipyramidal configuration. The six residues involved in the binding are in positions 1.... and 12; these residues are denoted by X...Y.X and -Z. The invariant Glu or Asp at position 12 provides two oxygens for liganding Ca (bidentate ligand).
  IPR002048:Calcium-binding EF-hand
The protozoan parasite that causes Chagas disease.rypanosoma cruzi.ontains a 24kDa protein that is recognised by antiera from both humans andexperimental animals infected with this organism. Near its C-terminus are two regions that have sequence similarity with E-F hand Ca2+-binding proteins . Indeed.he native trypanosome protein exhibits low Ca2+-binding capacity and high Ca2+-binding affinity.onsistent with binding via E-F hand structures. Immunofluorescence assays have suggested that the protein is localised to the trypanosomes flagellum. This observation.oupled with the proteins Ca2+-binding properties.uggests that it may participate in molecular processes associated with the high motility of the parasite . A set of similar 24 kDa proteins.ermed contained within the flagellum of Trypanosoma brucei. These contain three EF-hand Ca2+- binding domains and one degenerate EF-hand motif .
  IPR003299:Flagellar calcium-binding protein (calflagin)
This domain consists of a duplication of two EF-hand each unit is composed of two helices connected by a twelve-residue calcium-binding loop. The calcium ion in the EF-hand loop is coordinated in a pentagonal bipyramidal configuration. Many calcium-binding proteins contain an EF-hand type calcium-binding domain . These include: calbindin D9K.100 proteins such as calcyclin.olcalcin phl p 7 (a calcium-binding pollen allergen).steonectin.arvalbumin.almodulin family of proteins (troponin C.altractin.dc4p.yosin essential chain.alcineurin.ecoverin.eurocalcin).lasmodial-specific CaII-binding protein Cbp40.enta-EF-Hand proteins (sorcin.rancalcin.alpain).s well as multidomain proteins such as phosphoinositide-specific phospholipase C.ystrophin.b1 and alpha-actinin. The fold consists of four helices and an open array of two hairpins.
