Lenalidomide binding proteins identified by SPIDER assay

ABSTRACT: To assess whether SPIDER could capture protein-small molecule interaction in a complex environment, here we carried out the SPIDER assay by incubating biotin-Lenalidomide or a biotin control with HEK293T total lysate, followed by the use of biotin conjugated beads coupled with mass spectrometry to identify the interacting proteins

Protein-biomolecule interactions play pivotal roles in almost all biological processes. For a biomolecule of interest, the identification of the interacting protein(s) is essential. For this need, although many assays are available, highly robust and reliable methods are always desired. By combining a substrate-based proximity labeling activity from the pupylation pathway of Mycobacterium tuberculosis and the streptavidin (SA)-biotin system, we developed the Specific Pupylation as IDEntity Repor ...[more]

m6A binding proteins identified by SPIDER assay

Project description:To assess whether SPIDER could identify modified nucleic acids binding proteins within a complex environment, such as the cellular milieu, we sought to identify N6-methyladenosine (m6A) binding proteins within a total cell lysate. We performed SPIDER assay by incubating biotin-ssRNAs（with and without m6A modification）with the total lysate of YTDHFs (YTHDF1,YTHDF2 and YTHDF3)-overexpressed HEK293T cells

CobB interacting proteins identified by SPIDER assay

Project description:To assess whether SPIDER could detect transient interactions such as enzymes and their substrates, we examined the interactome of the E. coli protein deacetylase CobB. As the only member of the Sir2 family of deacetylases in E. coli, CobB is known to play a role in many different pathways but their interactors is still incompletely known. Here we applied SPIDER assay and a SILAC-based mass spectrometry strategy to capture and identify CobB Substrates. Biotinylated CobB was incubated with E. coli total lysate labeled with heavy stable isotope. As a control, free biotin was incubated with E. coli total lysate labeled with light stable isotope.

Pupylation sites on protein FKBP12

Project description:To test whether SPIDER can validate PSMI in a cell lysate, we examined the interaction between Rapamycin and FK-binding protein 12 (FKBP12) to test whether SPIDER can validate protein-small molecule interaction in total cell lysate.We performed SPIDER assay by incubating biotin-Rapamycin or biotin control with the total lysate of FKBP12-overexpressed HEK293T cells

CheA pupylation sites identified by SPIDER assay

Project description:We used CheAs and biotin-CheZ to validate the efficiency of SPIDER capturing protein-protein interaction. Pupylation sites on WT CheAs after SPIDER assay was identified by LC-MS/MS analysis, by searching for an additional mass of ~243 Da, which represents the three C-terminal residues of Pup, i. e., GGE, that covalently binds to adjacent lysine by pupylation. ）

Spider mite preliminary feeding experiment with mites reared on bean and two Arabidopsis thaliana accessions

Project description:We sequenced messenger RNA from mixed stages of the two-spotted spider mite (Tetranychus urticae) reared on bean (Phaseolus vulgaris cv California Red Kidney; the laboratory host plant for mites) and two Arabidopsis thaliana accessions which were considered to either be susceptible (Kondara) or resistant (Bla-2) to mite feeding. This pilot experiment was conducted to assess gene expression differences of mites grown on sensitive versus resistant Arabidopsis accessions, as well as differences in mites feeding on different host species. The expression data was used for gene model validation of genes predicted by EuGene in the spider mite genome and to assess gene expression levels. Examination of gene expression of spider mites reared on beans and two Arabidopsis accessions (Kondara and Bla-2).

Developmental stage-specific small RNA composition in the two-spotted spider mite (Tetranychus urticae)

Project description:We generated 38-bp Illumina reads from single messenger RNA libraries from three diverse developmental stages of the two-spotted spider mite to capture small RNA diversity across development. Adult, nymphal+larvae and embryonic stages were separated using sieves of various pore sizes, and mites of various developmental stages were carefully selected for small RNA library preparation. Samples were a mix of males and females to capture male and female patterns of small RNA composition and were reared on beans (Phaseolus vulgaris cv California Red Kidney). Small RNA reads were used for miRNA prediction, piRNA discovery, and for quantitation of small RNA-generating loci (i.e. expression across development). Examination of small RNA from spider mites of adult, embryonic and pooled larval/nymphal developmental stages.

Developmental stage-specific gene expression in the two-spotted spider mite (Tetranychus urticae)

Project description:We generated 77-bp Illumina reads from single messenger RNA libraries from four diverse developmental stages of the two-spotted spider mite to maximally capture the complement of transcribed sequences across development. Adult, nymphal, larvae and embryonic stages were separated using sieves of various pore sizes, and mites of various developmental stages were carefully selected for transcriptome library preparation. Samples were a mix of males and females to capture male and female patterns of transcription, and were reared on beans (Phaseolus vulgaris cv California Red Kidney). The RNA-Seq data was used for validation of gene models predicted by EuGene, and to study patterns of gene expression across development. Gene expression for spider mites from adult, nymph, larvae and embryonic developmental stages was examined (technical replicates were generated).
