The death-effector domain (DED) is a protein interaction domain found only in eukaryotes that regulates a variety of cellular signalling pathways. The DED domain is found in inactive procaspases and proteins that regulate caspase activation in the apoptosis cascade such as FAS-associating death domain-containing protein (FADD). FADD recruits procaspase 8 and procaspase 10 into a death induced signaling complex (DISC). This recruitment is mediated by a homotypic interaction between the procaspase DED and a second DED that is death effector domain in an adaptor protein that is directly associated with activated TNF receptors. Complex formation allows proteolytic activation of procaspase into the active caspase form which results in the initiation of apoptosis. Structurally the DED domain are a subclass of protein motif known as the death fold and contains 6 alpha helices, that closely resemble the structure of the Death domain (DD).
Intraflagellar transport (IFT) is a bidirectional motility along axoneme microtubules that is essential for the formation (ciliogenesis) and maintenance of most eukaryotic cilia and flagella. It is thought to be required to build all cilia that assemble within a membrane projection from the cell surface. Plasmodium falciparum cilia and the sperm flagella of Drosophila are examples of cilia that assemble in the cytoplasm and do not require IFT. The process of IFT involves movement of large protein complexes called IFT particles or trains from the cell body to the ciliary tip and followed by their return to the cell body. The outward or anterograde movement is powered by kinesin-2 while the inward or retrograde movement is powered by cytoplasmic dynein 2/1b. The IFT particles are composed of about 20 proteins organized in two subcomplexes called complex A and B.
Huntingtin(Htt) is the protein coded for in humans by the HTT gene, also known as the IT15 ("interesting transcript 15") gene. Mutated HTT is the cause of Huntington's disease (HD), and has been investigated for this role and also for its involvement in long-term memory storage.
Huntingtin-interacting protein 1 also known as HIP-1 is a protein that in humans is encoded by the HIP1 gene.
The BH3 interacting-domain death agonist, or BID, gene is a pro-apoptotic member of the Bcl-2 protein family. Bcl-2 family members share one or more of the four characteristic domains of homology entitled the Bcl-2 homology (BH) domains, and can form hetero- or homodimers. Bcl-2 proteins act as anti- or pro-apoptotic regulators that are involved in a wide variety of cellular activities.
Caspase-8 is a caspase protein, encoded by the CASP8 gene. It most likely acts upon caspase-3. CASP8 orthologs have been identified in numerous mammals for which complete genome data are available. These unique orthologs are also present in birds.
Caspase-3 is a caspase protein that interacts with caspase-8 and caspase-9. It is encoded by the CASP3 gene. CASP3 orthologs have been identified in numerous mammals for which complete genome data are available. Unique orthologs are also present in birds, lizards, lissamphibians, and teleosts.
Caspase-6 is an enzyme that in humans is encoded by the CASP6 gene. CASP6 orthologs have been identified in numerous mammals for which complete genome data are available. Unique orthologs are also present in birds, lizards, lissamphibians, and teleosts. Caspase-6 has known functions in apoptosis, early immune response and neurodegeneration in Huntington's and Alzheimer's disease.
Receptor-interacting serine/threonine-protein kinase 2 is an enzyme that in humans is encoded by the RIPK2 gene.
Endophilin-A3 is a protein that in humans is encoded by the SH3GL3 gene.
Ubiquitin-conjugating enzyme E2 K is a protein that in humans is encoded by the UBE2K gene.
Huntingtin-interacting protein 1-related protein is a protein that in humans is encoded by the HIP1R gene.
Intraflagellar transport protein 88 homolog is a protein that is encoded by the IFT88 gene.
Palmitoyltransferase ZDHHC17 is an enzyme that contains a DHHC domain that in humans is encoded by the ZDHHC17 gene.
Kinesin-like protein KIF17 is a protein that in humans is encoded by the KIF17 gene. KIF17 and its close relative, C. elegans OSM-3, are members of the kinesin-2 family of plus-end directed microtubule-based motor proteins. In contrast to heterotrimeric kinesin-2 motors, however, KIF17 and OSM-3 form distinct homodimeric complexes. Homodimeric kinesin-2 has been implicated in the transport of NMDA receptors along dendrites for delivery to the dendritic membrane, whereas both heterotrimeric and homodimeric kinesin-2 motors function cooperatively in anterograde intraflagellar transport (IFT) and cilium biogenesis.
Intraflagellar transport protein 20 homolog is a protein that in humans is encoded by the IFT20 gene. The gene is composed of 6 exons and is located on human chromosome 17p11.1. This gene is expressed in human brain, lung, kidney and pancreas, and lower expression were also detected in human placenta, liver, thymus, prostate and testis.

Intraflagellar transport protein 81 homolog is a protein that in humans is encoded by the IFT81 gene. Together with IFT74/72 it forms a core complex to build IFT particles which are required for cilium formation. Additionally, it interacts with basal body components as CEP170 which regulates the disassembly of the cilium.
Intraflagellar transport protein 80 homolog (IFT80), also known as WD repeat-containing protein 56, is a protein that in humans is encoded by the IFT80 gene.
FYVE, RhoGEF and PH domain-containing protein 2 (FGD2), also known as zinc finger FYVE domain-containing protein 4 (ZFYVE4), is a protein that in humans is encoded by the FGD2 gene.
