>PF10393 Matrilin_ccoil: Trimeric coiled-coil oligomerisation domain of matrilin; InterPro: IPR019466 This entry represents a short domain found the matrilin (cartilage matrix) proteins
It forms a coiled coil structure and contains a single cysteine residue at its start which is likely to form a di-sulphide bridge with a corresponding cysteine in an upstream EGF domain (IPR006209 from INTERPRO), thereby spanning the VWA domain of the protein (IPR002035 from INTERPRO).This domain is likely to be responsible for protein trimerisation []. ; PDB: 1AQ5_C.
>PF01601 Corona_S2: Coronavirus S2 glycoprotein; InterPro: IPR002552 The type I glycoprotein S of Coronavirus, trimers of which constitute the typical viral spikes, is assembled into virions through noncovalent interactions with the M protein
The spike glycoprotein is translated as a large polypeptide that is subsequently cleaved to S1 IPR002551 from INTERPRO and S2 []. Both chimeric S proteins appeared to cause cell fusion when expressed individually, suggesting that they were biologically fully active []. The spike is a type I membrane glycoprotein that possesses a conserved transmembrane anchor and an unusual cysteine-rich (cys) domain that bridges the putative junction of the anchor and the cytoplasmic tail [].; GO: 0006944 cellular membrane fusion, 0046813 virion attachment, binding of host cell surface receptor, 0016021 integral to membrane, 0019031 viral envelope; PDB: 2BEQ_B 2FXP_A 1ZVB_A 1WNC_D 1ZV8_H 1ZV7_B 1WYY_B 1ZVA_A 2BEZ_F 1WDG_A ....

This model represents the PhaE subunit of the heterodimeric class (class III) of polymerase for poly(R)-hydroxyalkanoic acids (PHAs), carbon and energy storage polymers of many bacteria. The most common PHA is polyhydroxybutyrate but about 150 different constituent hydroxyalkanoic acids (HAs) have been identified in various species. This model must be designated subfamily to indicate the heterogeneity of PHAs.
>PF07304 SRA1: Steroid receptor RNA activator (SRA1); InterPro: IPR009917 This entry consists of several hypothetical mammalian steroid receptor RNA activator proteins
The SRA-RNAs encode stable proteins that are widely expressed and upregulated in breast cancer cell lines. SRA-RNA is a steroid receptor co-activator which acts as a functional RNA. This domain is also found at the C terminus of Sec31, a component of the coat protein complex II (COPII, which promotes the formation of transport vesicles from the endoplasmic reticulum (ER). COPII has two main functions, the physical deformation of the endoplasmic reticulum membrane into vesicles and the selection of cargo molecules. ; PDB: 2YRU_A.

>PF04513 Baculo_PEP_C: Baculovirus polyhedron envelope protein, PEP, C terminus ; InterPro: IPR007601 Polyhedra are large crystalline occlusion bodies containing nucleopolyhedrovirus virions, and surrounded by an electron-dense structure called the polyhedron envelope or polyhedron calyx
The polyhedron envelope (associated) protein PEP is thought to be an integral part of the polyhedron envelope. PEP is concentrated at the surface of polyhedra, and is thought to be important for the proper formation of the periphery of polyhedra. It is thought that PEP may stabilise polyhedra and protect them from fusion or aggregation [].; GO: 0005198 structural molecule activity, 0019028 viral capsid, 0019031 viral envelope
>PF05377 FlaC_arch: Flagella accessory protein C (FlaC); InterPro: IPR008039 Although archaeal flagella appear superficially similar to those of bacteria, they are quite distinct []
In several archaea, the flagellin genes are followed immediately by the flagellar accessory genes flaCDEFGHIJ. The gene products may have a role in translocation, secretion, or assembly of the flagellum. FlaC is a protein whose exact role is unknown but it has been shown to be membrane-associated (by immuno-blotting fractionated cells) [].

This model describes a domain found in some proteins associated with polyhydroxyalkanoate (PHA) granules in a subset of species that have PHA inclusion granules. Included are two tandem proteins of Pseudomonas oleovorans, PhaI and PhaF, and their homologs in related species. PhaF proteins have a low-complexity C-terminal region with repeats similar to AAAKP.

This protein forms a dimer characterised by a long four-helix bundle, composed of two helices from each monomer. CheZ dephosphorylates CheY in a reaction that is essential to maintain a continuous chemotactic response to environmental changes. It is thought that CheZ's conserved residue Gln 147 orientates a water molecule for nucleophilic attack at the CheY active site. ; GO: 0003824 catalytic activity, 0050920 regulation of chemotaxis, 0009288 bacterial-type flagellum; PDB: 1KMI_Z 2FMK_B 2PMC_F.
>PF04380 BMFP: Membrane fusogenic activity; InterPro: IPR007475 BMFP consists of two structural domains, a coiled-coil C-terminal domain via which the protein self-associates as a trimer, and an N-terminal domain disordered at neutral pH but adopting an amphipathic alpha-helical structure in the presence of phospholipid vesicles, high ionic strength, acidic pH or SDS
BMFP interacts with phospholipid vesicles though the predicted amphipathic alpha-helix induced in the N-terminal half of the protein and promotes aggregation and fusion of vesicles in vitro.
>PF06008 Laminin_I: Laminin Domain I; InterPro: IPR009254 Laminins are glycoproteins that are major constituents of the basement membrane of cells
Laminins are trimeric molecules; laminin-1 is an alpha1 beta1 gamma1 trimer. It has been suggested that the domains I and II from laminin A, B1 and B2 may come together to form a triple helical coiled-coil structure []. Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organisation of cells into tissues during embryonic development by interacting with other extracellular matrix components.; GO: 0005102 receptor binding, 0030155 regulation of cell adhesion, 0030334 regulation of cell migration, 0045995 regulation of embryonic development, 0005606 laminin-1 complex

>PF00509 Hemagglutinin: Haemagglutinin; InterPro: IPR001364 Haemagglutinin (HA) is one of two main surface fusion glycoproteins embedded in the envelope of influenza viruses, the other being neuraminidase (NA)
There are sixteen known HA subtypes (H1-H16) and nine NA subtypes (N1-N9), which together are used to classify influenza viruses (e.g. H5N1). The antigenic variations in HA and NA enable the virus to evade host antibodies made to previous influenza strains, accounting for recurrent influenza epidemics []. The HA glycoprotein is present in the viral membrane as a single polypeptide (HA0), which must be cleaved by the host's trypsin-like proteases to produce two peptides (HA1 and HA2) in order for the virus to be infectious. Once HA0 is cleaved, the newly exposed N-terminal of the HA2 peptide then acts to fuse the viral envelope to the cellular membrane of the host cell, which allows the viral negative-stranded RNA to infect the host cell. The type of host protease can influence the infectivity and pathogenicity of the virus. The haemagglutinin glycoprotein is a trimer containing three structurally distinct regions: a globular head consisting of anti-parallel beta-sheets that form a beta-sandwich with a jelly-roll fold (contains the receptor binding site and the HA1/HA2 cleavage site); a triple-stranded, coiled-coil, alpha-helical stalk; and a globular foot composed of anti-parallel beta-sheets [, ]. Each monomer consists of an intact HA0 polypeptide with the HA1 and HA2 regions linked by disulphide bonds. The N terminus of HA1 provides the central strand in the 5-stranded globular foot, while the rest of the HA1 chain makes its way to the 8-stranded globular head. HA2 provides two alpha helices, which form part of the triple-stranded coiled-coil that stabilises the trimer, its C terminus providing the remaining strands of the 5-stranded globular foot. This entry represents the entire haemagglutinin protein (HA0) consisting of both the HA1 and HA2 regions, as found in influenza A and B viruses.; GO: 0046789 host cell surface receptor binding, 0019064 viral envelope fusion with host membrane, 0019031 viral envelope; PDB: 2WR5_A 2IBX_A 2WR0_B 2WR1_C 2XN9_F 2WRF_I 3S11_E 3BT6_A 3SM5_E 2FK0_H ....
