Enrichment of NICD4 interacting proteins by three different methods.

ABSTRACT: There are several methods to bring down the bait and interactors from the cell lysates, each with its own advantages and disadvantages. Recently, the most commonly used method is one step AP, TAP and proximity-labeling. In order to analyze the Strengths and weaknesses of the three methods, fusion proteins were constructed by NICD4 with FLAG, SFB (S tag-2x Flag tag-SBP tag) and TurboID respectively, NICD4 and its interactors were obtained by purification. By analyzing these proteins, we believe that SFB-TAP is the most reliable and effective method to identify interacting proteins.

STAR protocols 20220719 3

Identification of protein interactors is fundamental to understanding their functions. Here, we describe a modified protocol for tandem affinity purification coupled with mass spectrometry (TAP/MS), which includes two-step purification. We detail the S-, 2×FLAG-, and Streptavidin-Binding Peptide (SBP)- tandem tags (SFB-tag) system for protein purification. This protocol can be used to identify protein interactors and establish a high-confidence protein-protein interaction network based on comput ...[more]

293T NME4 TAP-MS and TurboID-MS

Project description:To identify interacting proteins of NME4 in human cell lines, we using tandem affinity purification followed by mass spectrometry (TAP-MS) in HEK293T cells. We established stable cell line which expressing NME4 gene fused with SFB triple tags (S tag-2x Flag tag-SBP tag) or TurboID. We isolated, combined, and affinity-purified the membrane and soluble fractions using TAP. We identified proteins associated with the bait in the isolated complexes using MS and searched the uniprot human database for these proteins.

Three acyltransferases and a nitrogen responsive regulator are implicated in nitrogen starvation-induced triacylglycerol accumulation in Chlamydomonas

Project description:Three acyltransferases, DGAT1, DGTT1, and PDAT1, are induced by nitrogen starvation and are likely to have a role in TAG accumulation based on their patterns of expression. Each gene also shows increased mRNA abundance in other TAG-accumulating conditions (-S, -P, -Zn, -Fe). Insertional mutants, pdat1-1 and pdat1-2, accumulate 25% less TAG compared to the parent strain, D66+, which demonstrates the relevance of the trans-acylation pathway in Chlamydomonas. The biochemical functions of DGTT1 and PDAT1 were validated by rescue of oleic acid sensitivity and restoration of TAG accumulation in a yeast strain lacking all acyltransferase activity. Time course analysis suggest than an SBP domain transcription factor protein, whose mRNA increases precede that of other genes like DGAT1, is a candidate regulator of the N-deficiency response. An insertional mutant, nrr1-1, accumulates only 50% of the TAG compared to the parental strain in N-starvation conditions and is unaffected by other nutrient stresses, suggesting the operation of multiple signaling pathways leading to stress-induced TAG accumulation. Sampling of Chlamydomonas 2137 cultivated in TAP, N-Free TAP or TAP with varying amounts of N.

USP11 deubiquitinates monoubiquitinated SPRTN to repair DNA-protein crosslinks

Project description:DNA-protein crosslinks (DPCs) are toxic DNA lesions that interfere with DNA metabolic processes such as replication, transcription, and recombination. SPRTN is a replication-coupled DNA-dependent metalloprotease that degrades proteins crosslinked to DNA to promote DPC repair. SPRTN function is tightly regulated by a monoubiquitin switch that controls SPRTN chromatin accessibility during DPC repair. The deubiquitinase regulating SPRTN function in DPC repair is unknown. To identify SPRTN modifiers, we performed tandem-affinity purification and mass spectrometry (TAP-MS) analysis of SFB (S-FLAG-streptavidin binding peptide)-tagged SPRTN expressed in HEK 293T cells. We screened the MS list for proteins that are known to function as a deubiquitinase and identified only one potential SPRTN modifier, USP11 deubiquitinase. A reciprocal TAP-MS analysis of SFB-USP11 expressed in HEK 293T cells treated with camptothecin (CPT) immunoprecipitated SPRTN. USP11 interacts with SPRTN and cleaves monoubiquitinated SPRTN in cells and in vitro. USP11 depletion impaired SPRTN deubiquitination in response to formaldehyde-induced DPCs. Loss of USP11 causes an accumulation of unrepaired DPCs and cellular hypersensitivity to treatment with DPC-inducing agents. Our findings elucidates the function of USP11 in the regulation of SPRTN monoubiquitination and SPRTN-mediated DPC repair.
