chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

Bacillus thuringiensis crystal 6Aa (Cry6Aa) toxin, and similar proteins; This model includes pesticidal Cry6Aa toxin from Bacillus thuringiensis, one of the many parasporal crystal (Cry) toxins produced during the sporulation phase of growth. Many of these proteins are toxic to numerous insect species and have been effectively used as proteinaceous insecticides to directly kill insect pests; some have been used to control insect growth on transgenic agricultural plants. Cry6Aa exists as a protoxin, which is activated by cleavage using trypsin. Structure studies for Cry6Aa support a mechanism of action by pore formation, similar to cytolysin A (ClyA)-type alpha pore-forming toxins (alpha-PFTs) such as HblB, and bioassay and mutation studies show that Cry6Aa is an active pore-forming toxin. Cry6Aa shows atypical features compared to other members of alpha-PFTs, including internal repeat sequences and small loop regions within major alpha helices.

HOOK protein coiled-coil region; This family consists of several HOOK1, 2 and 3 proteins from different eukaryotic organizms. The different members of the human gene family are HOOK1, HOOK2 and HOOK3. Different domains have been identified in the three human HOOK proteins, and it was demonstrated that the highly conserved NH2-domain mediates attachment to microtubules, whereas this central coiled-coil motif mediates homodimerization and the more divergent C-terminal domains are involved in binding to specific organelles (organelle-binding domains). It has been demonstrated that endogenous HOOK3 binds to Golgi membranes, whereas both HOOK1 and HOOK2 are localized to discrete but unidentified cellular structures. In mice the Hook1 gene is predominantly expressed in the testis. Hook1 function is necessary for the correct positioning of microtubular structures within the haploid germ cell. Disruption of Hook1 function in mice causes abnormal sperm head shape and fragile attachment of the flagellum to the sperm head. This entry includes the central coiled-coiled domain and the divergent C-terminal domain.

reticulocyte binding/rhoptry protein; This model represents a group of paralogous families in plasmodium species alternately annotated as reticulocyte binding protein, 235-kDa family protein and rhoptry protein. Rhoptry protein is localized on the cell surface and is extremely large (although apparently lacking in repeat structure) and is important for the process of invasion of the RBCs by the parasite. These proteins are found in P. falciparum, P. vivax and P. yoelii.
