Pages: 571-83
Protein Domain
Type: Family
Description: This is a plant family of proteins which includes DWD HYPERSENSITIVE TO UV-B 1 protein (DHU1) from Arabidopsis. DHU1 may act as a substrate receptor of a CUL4-RING E3 ubiquitin-protein ligase (CRL4) complex involved in the negative regulation of cellular responses to ultraviolet-B (UV-B) illumination, likely in coordination with RUP1 [, ]. It interacts with COP1 and probably prevents the formation of active UVR8-COP1 complex, thus avoiding UVR8-COP1-mediated positive regulation of UV-B responses [].

Title: SPAs promote thermomorphogenesis by regulating the phyB-PIF4 module in Arabidopsis.
Volume: 147
Issue: 19
Protein Domain
Type: Family
Description: In Arabidopsis, SPA1/2/3/4 play a central role in suppression of photomorphogenesis. SPA1 and SPA2 predominate in dark-grown seedlings, whereas SPA3 and SPA4 prevalently regulate the elongation growth in adult plants []. SPAs contain a kinase-like domain, a coiled-coil domain and the WD-repeats. SPAs and COP1 (a ring finger E3 ubiquitin ligase) can form homo- and heterodimers via their respective coiled-coil domains, and the COP1/SPA complex forms a tetramer of two COP1 and two SPA proteins []. The SPA proteins can self-associate or interact with each other, forming a heterogeneous group of SPA-COP1 complexes []. Besides recognizing substrates, both COP1 and SPA bind DDB1 in the CUL4 complex through their C-terminal WD-repeat domains. They serve as DDB1-CUL4-associated factors (DCAFs) similar to other substrate adaptors in CUL4-based E3 ligases. SPA1 interacts with photoreceptor cry2 via its kinase-like domain, with cry1 via its WD-repeat domain and with phytochromes possibly via both []. SPAs have also been shown to regulate the phyB-PIF4 module at high ambient temperature [].

Protein Domain
Type: Domain
Description: This domain identifies a group of proteins, which are described as: General vesicular transport factor, Transcytosis associate protein (TAP) and Vesicle docking protein. This myosin-shaped molecule consists of an N-terminal globular head region, a coiled-coil tail which mediates dimerisation, and a short C-terminal acidic region []. p115 tethers COP1 vesicles to the Golgi by binding the coiled coil proteins giantin (on the vesicles) and GM130 (on the Golgi), via its C-terminal acidic region. It is required for intercisternal transport in the Golgi stack. This domain is found in the acidic C-terminal region, which binds to the golgins giantin and GM130. p115 is thought to juxtapose two membranes by binding giantin with one acidic region, and GM130 with another [].

Description: Proteins synthesised on the ribosome and processed in the endoplasmic reticulum are transported from the Golgi apparatus to the trans-Golgi network (TGN), and from there via small carrier vesicles to their final destination compartment. This traffic is bidirectional, to ensure that proteins required to form vesicles are recycled. Vesicles have specific coat proteins (such as clathrin or coatomer) that are important for cargo selection and direction of transfer []. While clathrin mediates endocytic protein transport, and transport from ER to Golgi, coatomers primarily mediate intra-Golgi transport, as well as the reverse Golgi to ER transport of dilysine-tagged proteins []. For example, the coatomer COP1 (coat protein complex 1) is responsible for reverse transport of recycled proteins from Golgi and pre-Golgi compartments back to the ER, while COPII buds vesicles from the ER to the Golgi []. Coatomers reversibly associate with Golgi (non-clathrin-coated) vesicles to mediate protein transport and for budding from Golgi membranes []. Activated small guanine triphosphatases (GTPases) attract coat proteins to specific membrane export sites, thereby linking coatomers to export cargos. As coat proteins polymerise, vesicles are formed and budded from membrane-bound organelles. Coatomer complexes also influence Golgi structural integrity, as well as the processing, activity, and endocytic recycling of LDL receptors. In mammals, coatomer complexes can only be recruited by membranes associated to ADP-ribosylation factors (ARFs), which are small GTP-binding proteins. Coatomer complexes are hetero-oligomers composed of at least an alpha, beta, beta', gamma, delta, epsilon and zeta subunits. This group represents the coatomer beta subunit.
