EXS family; We have named this region the EXS family after (ERD1, XPR1, and SYG1). This family includes C-terminus portions from the SYG1 G-protein associated signal transduction protein from Saccharomyces cerevisiae, and sequences that are thought to be murine leukaemia virus (MLV) receptors (XPR1). N-terminus portions from these proteins are aligned in the SPX pfam03105 family. The previously noted similarity between SYG1 and MLV receptors over their whole sequences is thus borne out in pfam03105 and this family. While the N-termini aligned in pfam03105 are thought to be involved in signal transduction, the role of the C-terminus sequences aligned in this family is not known. This region of similarity contains several predicted transmembrane helices. This family also includes the ERD1 (ERD: ER retention defective) yeast proteins. ERD1 proteins are involved in the localization of endogenous endoplasmic reticulum (ER) proteins. erd1 null mutants secrete such proteins even though they possess the C-terminal HDEL ER lumen localization label sequence. In addition, null mutants also exhibit defects in the Golgi-dependent processing of several glycoproteins, which led to the suggestion that the sorting of luminal ER proteins actually occurs in the Golgi, with subsequent return of these proteins to the ER via `salvage' vesicles.

SPX domain; We have named this region the SPX domain after SYG1, Pho81 and XPR1. This 180 residue long domain is found at the amino terminus of a variety of proteins. In the yeast protein SYG1, the N-terminus directly binds to the G-protein beta subunit and inhibits transduction of the mating pheromone signal. Similarly, the N-terminus of the human XPR1 protein binds directly to the beta subunit of the G-protein heterotrimer leading to increased production of cAMP. These findings suggest that all the members of this family are involved in G-protein associated signal transduction. The N-termini of several proteins involved in the regulation of phosphate transport, including the putative phosphate level sensors PHO81 from Saccharomyces cerevisiae and NUC-2 from Neurospora crassa, are also members of this family. The SPX domain of S. cerevisiae low-affinity phosphate transporters Pho87 and Pho90 auto-regulates uptake and prevents efflux. This SPX dependent inhibition is mediated by the physical interaction with Spl2 NUC-2 contains several ankyrin repeats pfam00023. Several members of this family are annotated as XPR1 proteins: the xenotropic and polytropic retrovirus receptor confers susceptibility to infection with murine xenotropic and polytropic leukaemia viruses (MLV). Infection by these retroviruses can inhibit XPR1-mediated cAMP signalling and result in cell toxicity and death. The similarity between SYG1, phosphate regulators and XPR1 sequences has been previously noted, as has the additional similarity to several predicted proteins, of unknown function, from Drosophila melanogaster, Arabidopsis thaliana, Caenorhabditis elegans, Schizosaccharomyces pombe, and Saccharomyces cerevisiae, and many other diverse organizms. In addition, given the similarities between XPR1 and SYG1 and phosphate regulatory proteins, it has been proposed that XPR1 might be involved in G-protein associated signal transduction and may itself function as a phosphate sensor.

2-344 1.19e-52

SPX domain of the plant protein PHOSPHATE1 (PHO1); This region has been named the SPX domain after (Syg1, Pho81 and XPR1). The domain is found at the amino terminus of a variety of proteins. The PHO1 gene family conserved in plants is involved in a variety of processes, most notably the transport of inorganic phosphate from the root to the shoot of the plant and mediating the response to low levels of inorganic phosphate. More recently it has become evident that PHO1 gene families have diverged in various plants and may play roles in stress response as well as the stomatal response to abscisic acid.

EXS family; We have named this region the EXS family after (ERD1, XPR1, and SYG1). This family includes C-terminus portions from the SYG1 G-protein associated signal transduction protein from Saccharomyces cerevisiae, and sequences that are thought to be murine leukaemia virus (MLV) receptors (XPR1). N-terminus portions from these proteins are aligned in the SPX pfam03105 family. The previously noted similarity between SYG1 and MLV receptors over their whole sequences is thus borne out in pfam03105 and this family. While the N-termini aligned in pfam03105 are thought to be involved in signal transduction, the role of the C-terminus sequences aligned in this family is not known. This region of similarity contains several predicted transmembrane helices. This family also includes the ERD1 (ERD: ER retention defective) yeast proteins. ERD1 proteins are involved in the localization of endogenous endoplasmic reticulum (ER) proteins. erd1 null mutants secrete such proteins even though they possess the C-terminal HDEL ER lumen localization label sequence. In addition, null mutants also exhibit defects in the Golgi-dependent processing of several glycoproteins, which led to the suggestion that the sorting of luminal ER proteins actually occurs in the Golgi, with subsequent return of these proteins to the ER via `salvage' vesicles.

SPX domain; We have named this region the SPX domain after SYG1, Pho81 and XPR1. This 180 residue long domain is found at the amino terminus of a variety of proteins. In the yeast protein SYG1, the N-terminus directly binds to the G-protein beta subunit and inhibits transduction of the mating pheromone signal. Similarly, the N-terminus of the human XPR1 protein binds directly to the beta subunit of the G-protein heterotrimer leading to increased production of cAMP. These findings suggest that all the members of this family are involved in G-protein associated signal transduction. The N-termini of several proteins involved in the regulation of phosphate transport, including the putative phosphate level sensors PHO81 from Saccharomyces cerevisiae and NUC-2 from Neurospora crassa, are also members of this family. The SPX domain of S. cerevisiae low-affinity phosphate transporters Pho87 and Pho90 auto-regulates uptake and prevents efflux. This SPX dependent inhibition is mediated by the physical interaction with Spl2 NUC-2 contains several ankyrin repeats pfam00023. Several members of this family are annotated as XPR1 proteins: the xenotropic and polytropic retrovirus receptor confers susceptibility to infection with murine xenotropic and polytropic leukaemia viruses (MLV). Infection by these retroviruses can inhibit XPR1-mediated cAMP signalling and result in cell toxicity and death. The similarity between SYG1, phosphate regulators and XPR1 sequences has been previously noted, as has the additional similarity to several predicted proteins, of unknown function, from Drosophila melanogaster, Arabidopsis thaliana, Caenorhabditis elegans, Schizosaccharomyces pombe, and Saccharomyces cerevisiae, and many other diverse organizms. In addition, given the similarities between XPR1 and SYG1 and phosphate regulatory proteins, it has been proposed that XPR1 might be involved in G-protein associated signal transduction and may itself function as a phosphate sensor.

SPX domain of the plant protein PHOSPHATE1 (PHO1); This region has been named the SPX domain after (Syg1, Pho81 and XPR1). The domain is found at the amino terminus of a variety of proteins. The PHO1 gene family conserved in plants is involved in a variety of processes, most notably the transport of inorganic phosphate from the root to the shoot of the plant and mediating the response to low levels of inorganic phosphate. More recently it has become evident that PHO1 gene families have diverged in various plants and may play roles in stress response as well as the stomatal response to abscisic acid.

In the yeast protein Syg1, the N-terminus directly binds to the G-protein beta subunit and inhibits transduction of the mating pheromone signal. Similarly, the N-terminus of the human XPR1 protein binds directly to the beta subunit of the G-protein heterotrimer leading to increased production of cAMP. These findings suggest that members of this family are involved in G-protein associated signal transduction. The N-termini of several proteins involved in the regulation of phosphate transport, including the putative phosphate level sensors Pho81 from Saccharomyces cerevisiae and NUC-2 from Neurospora crassa, are also members of this family. The SPX domain of S. cerevisiae low-affinity phosphate transporters Pho87 and Pho90 auto-regulates uptake and prevents efflux. This SPX dependent inhibition is mediated by the physical interaction with Spl2. NUC-2 contains several ankyrin repeats. Several members of this family are annotated as XPR1 proteins: the xenotropic and polytropic retrovirus receptor confers susceptibility to infection with xenotropic and polytropic murine leukaemia viruses (MLV). Infection by these retroviruses can inhibit XPR1-mediated cAMP signaling and result in cell toxicity and death. The similarity between Syg1, phosphate regulators and XPR1 sequences has been previously noted, as has the additional similarity to several predicted proteins, of unknown function, from Drosophila melanogaster, Arabidopsis thaliana, Caenorhabditis elegans, Schizosaccharomyces pombe, S. cerevisiae, and many other diverse organisms.
