Extra Large G-Protein Interactome Reveals Multiple Stress Response Function and Partner-Dependent XLG Subcellular Localization

The three-member family of Arabidopsis extra-large G proteins (XLG1-3) defines the prototype of an atypical Gα subunit in the heterotrimeric G protein complex. Recent evidence indicate that XLG subunits operate along with its Gβγ dimer in root morphology, stress responsiveness, and cytokinin induced development, however downstream targets of activated XLG proteins in the stress pathways are rarely known. To assemble a set of candidate XLG-targeted proteins, a yeast two-hybrid complementation-based screen was performed using XLG protein baits to query interactions between XLG and partner protein found in glucose-treated seedlings, roots, and Arabidopsis cells in culture. Seventy two interactors were identified and >60% of a test set displayed in vivo interaction with XLG proteins. Gene co-expression analysis shows that >70% of the interactors are positively correlated with the corresponding XLG partners. Gene Ontology enrichment for all the candidates indicates stress responses and posits a molecular mechanism involving a specific set of transcription factor partners to XLG. Genes encoding two of these transcription factors, SZF1 and 2, require XLG proteins for full NaCl-induced expression. The subcellular localization of the XLG proteins in the nucleus, endosome, and plasma membrane is dependent on the specific interacting partner.

“…There are still many questions about the role of PABP in initiation, its interactions with various initiation factors and other proteins, such as the PAM2-domain containing Early Responsive to Dehydration 15 (ERD15) family members (Aalto et al, 2012). PABP function likely extends beyond initiation.…”

Protein synthesis is a fundamental process in gene expression that depends upon the abundance and accessibility of the mRNA transcript as well as the activity of many protein and RNA-protein complexes. Here we focus on the intricate mechanics of mRNA translation in the cytoplasm of higher plants. This chapter includes an inventory of the plant translational apparatus and a detailed review of the translational processes of initiation, elongation, and termination. The majority of mechanistic studies of cytoplasmic translation have been carried out in yeast and mammalian systems. The factors and mechanisms of translation are for the most part conserved across eukaryotes; however, some distinctions are known to exist in plants. A comprehensive understanding of the complex translational apparatus and its regulation in plants is warranted, as the modulation of protein production is critical to development, environmental plasticity and biomass yield in diverse ecosystems and agricultural settings.

“…The members of the ERD15 family are characterized by similar sizes (120-170 amino acids), and they all share a highly conserved domain structure with the PAM2 motif (an acidic domain) in the N-terminus, which is also found in IbERD15. Similar to other ERD15 genes, IbERD15 also contains a 12-amino acid core sequence (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) in the conserved PAM2 motif, suggesting that it might have a similar function to that of other members of the ERD15 family (Aalto et al, 2012).…”

ABSTRACT. The early response to the dehydration 15 (ERD15) gene is widely involved in the processes of signal transduction, programmed cell death, gene transcription, and stress tolerance in plants. In a previous study, the ERD15 gene was shown to be an important regulator of the abscisic acid response and salicylic acid-dependent defense pathway, acting as an important negative regulator of abscisic acid. The complete IbERD15 gene (accession No. KF723428) was isolated by reverse transcription-polymerase chain reaction. The IbERD15 gene contains an open reading frame of 504 bp, encodes a peptide of 167 amino acids, and has a molecular mass of 18.725 kDa. The transcript levels of the IbERD15 gene in a variety of tissues were examined by digital gene expression profiling. The roots of the sweet potato were treated by 3 degrees of polyethylene glycol, and the results indicate that the IbERD15 gene might play an important role in the defense response to drought stress. Moreover, the IbERD15 gene was successfully transformed into yeast cells for analysis of drought tolerance in transgenic yeast.
