Caption
Immunoprecipitation was performed on nuclear extracts from the cell line K562 using the antibody HPA008472. Lane 1: input nuclear lysate. Lane 2: material immunoprecipitated with antibody. Lane 3: material immunoprecipitated using control IgG. Marked bands were excised from gel and subjected to analysis by mass spectrometry. Target molecular weight: 77.0.
Submitter comment
We analyzed the whole marked band, including what looks to be immunoreactive signal in the IgG control.
Reviewer comment
Marked band looks to also be detected in the IgG control. However, in the subsequent mass-spec analysis, SKIL is found to be specifically enriched in the IP and not in the IgG control.

Caption
IP followed by mass spectrometry. Briefly, protein was immunoprecipitated from K562 nuclear cell lysates using the antibody HPA008472, and the IP fraction was loaded on a 10% polyacrylamide gel (NuPAGEBis-Tris Gel) and separated with an Invitrogen NuPAGE electrophoresis system. The gel was stained by ColloidialCoomassie G-250 stain, gel fragments corresponding to the bands indicated were excised. Then proteins were trypsinized using the in-gel digestion method. Digested proteins were analyzed on an Orbitrap Elite mass spectrometer (Thermo Scientific) by the nanoLC-ESI-MS/MS technique. Peptides were identified by the SEQUEST algorithm and filtered with a high confidence threshold (Peptide false discovery rate < 1%, 2 unique peptides per protein minimum, mass error < 10 ppm).
Submitter comment
SHMT2, KIF20A, MORC3, SF3B3, PARN, SUGP1, CIZ1 and G3BP1 are not DNA binding transcription factors.
Reviewer comment
CIZ1 might be a sequence-specific TF? https://www.ncbi.nlm.nih.gov/pubmed/12824700. However, the ENCODE Antibody Review panel reviewed the reference on June 26, 2017 and determined that more recent papers consider CIZ1 a co-activator and the degenerate consensus motif cited in the reference is not convincing evidence of it being a sequence-specific DNA binding protein.

a) Western blot analysis of nuclear lysates prepared from multiple cells lines loaded in the order: GM12878, K562, HepG2, Liver using the antibody HPA008472.
Reviewer comment
Major band smaller than expected size of ~77kD (not indicated on image or caption) but there are multiple bands.
