Domain Architecture (Details)
InterPro domains unassigned to SynO:
Intermediate filaments (IF) are proteins which are primordial components of the cytoskeleton and the nuclear envelope. They generally form filamentous structures 8 to 14 nm wide.IF proteins are members of a very large multigene family of proteins which has been subdivided in five major subgroups:Type I: Acidic cytokeratins.Type II: Basic cytokeratins.Type III: Vimentin.esmin.lial fibrillary acidic protein (GFAP).eripherin.nd plasticin.Type IV: Neurofilaments L. and M.lpha-internexin and nestin.Type V: Nuclear lamins A.1.2 and C.All IF proteins are structurally similar in that they consist of: a central rod domain comprising some 300 to 350 residues which is arranged in coiled-coiled alpha-helices.ith at least two short characteristic interruptions; a N-terminal non-helical domain (head) of variable length; and a C-terminal domain (tail) which is also non-helical.nd which shows extreme length variation between different IF proteins.While IF proteins are evolutionary and structurally related.hey have limited sequence homologies except in several regions of the rod domain.

Keratins are a well known group of intermediate filament proteins. Like actin filaments.eratins are flexible but provide a firm cell skeleton.Unlike actin.owever.o known keratins are associated with motor functions. Approximately 10 keratins form the basis of hair or claw.ith a further 20 found in internal body cavity epithelia. They are alsofound at desmosomes and hemi-desmosomes (cell/cell and cell/matrix contacts respectively) .Type I keratins are a group of acidic intermediate filament proteins thatexist as chains of hetero-dimers with basic type II keratins. Each typeI keratin consists of head-.od- and tail-like structures.he rod beingconstructed from three linked coils: 1A.B and 2. Type I proteins are associated with a number of inherited developmental disorders.uch as baldness.eading of hair.nd skin blistering.
  IPR002957:Keratin, type I
Intermediate filaments (IF) are proteins which are primordial components of the cytoskeleton and the nuclear envelope. They generally form filamentous structures 8 to 14 nm wide. Type II keratins are the basic or neutral courterparts to the acidic type I keratins. Each type II keratin forms a heterodimer with a specific acidic keratin.nd the heterodimers are organised into tetramers and then into chains . Type II keratins consist of head-.od- and tail-like structures.he rod being constructed from three linked coils: 1A.B and 2. The head and tail structures of the type 2 keratins are highly variable low-complexity regions.
  IPR003054:Type II keratin
This domain consists of several insect apolipoprotein-III sequences. Exchangeable apolipoproteins constitute a functionally important family of proteins that play critical roles in lipid transport and lipoprotein metabolism. Apolipophorin III (apoLp-III) is a prototypical exchangeable apolipoprotein found in many insect species that functions in transport of diacylglycerol (DAG) from the fat body lipid storage depot to flight muscles in the adult life stage .The SSF signature in this entry is currently under review. Please be aware that some of the protein hits may be false positives.
  IPR011000:Apolipophorin III-like
In prokaryotes.he nucleotide exchange factor GrpE and the chaperone DnaJ are required for nucleotide binding of the molecular chaperone DnaK . The DnaK reaction cycle involves rapid peptide binding and release.hich is dependent upon nucleotide binding. DnaJ accelerates the hydrolysis of ATP by DnaK.hich enables the ADP-bound DnaK to tightly bind peptide. GrpE catalyses the release of ADP from DnaK.hich is required for peptide release. In eukaryotes.rpE is essential for mitochondrial Hsp70 function.owever the cytosolic Hsp70 homologues are GrpE-independent. GrpE binds as a homodimer to the ATPase domain of DnaK.nd may interact with the peptide-binding domain of DnaK. GrpE accomplishes nucleotide exchange by opening the nucleotide-binding cleft of DnaK. GrpE is comprised of two domains.he N-terminal coiled coil domain.hich may facilitate peptide release.nd the C-terminal head domain.hich forms part of the contact surface with the ATPase domain of DnaK. This entry represents the N-terminal coiled-coil domain.
