Project description:We have performed ChIP-sequencing analysis on human FOXN2 and RFX1 target sequences in human embryonic kidney HEK293T cells stably expressing Streptavidin-S-FLAG (SFB) triple-tagged proteins. The NGS sequencing were performed on Illumina MiSeq desktop sequencer.
Project description:To identify the site(s) of O-GlcNAcylation on PGK1, we transiently co-expressed Flag-tagged PGK1 and OGT in HEK293T cells. After immunoprecipitation using anti-Flag M2 beads and in-gel trypsin digestion, resulted peptides were subjected to mass spectrometry analysis
Project description:To identify the interaction proteins of TFEB, HEK293T cells transiently expressing TFEB-Flag were immunoprecipitated with anti-Flag beads. The beeds were used to do a LC/MS.
Project description:NPAC ChIP were performed by anti-Flag and anti-HA tandem affinity purification from HeLa stably expressing Flag-HA tagged NPAC from pOZ-N vector, and enrichement on chromosome 3, 21, and 22 were determined by chip microarray analysis using Affymatrix HumanTiling 2.0 arrays
Project description:The S831 phosphosite on AFF4 lies within a disordered region adjacent to the ENL/AF9 binding site. We therefore hypothesized that phosphorylation may regulate protein:protein interactions within the Super Elongation Complex. To investigate this, HEK293T cells expressing RFP negative control, FLAG-tagged AFF4-WT or FLAG-tagged AFF4-A-mutant were stimulated with insulin for 30 min followed by immunoprecipitation and analysis of interacting proteins by LC-MS/MS.
