Role of S-nitrosylation of Kdm1a in tailfin regeneration in adult zebrafish.

A MS/MS fragmentation spectrum for the Cys334-containing peptide of Kdm1a. Peptide sequence is shown at the top left of the spectrum, with the annotation of the identified matched amino terminus-containing ions (b ions) in black and the carboxyl terminus-containing ions (y ions) in red. The spectrum confirms the identity of the peptides CPLYEAN and the labeled C as S-nitrosylated cysteine. B Line graph reporting the quantification of Kdm1a S-nitrosylation (normalized by total Kdm1a) and Kdm1a activity during tailfin regeneration. C Western blotting (WB) for S-nitrosylated Kdm1a in uninjured and at 3, 5, and 10 dpa. Samples were previously immunoprecipitated (IP) for Kdm1a. IP with IgG and input were used as controls. D–F WB for Kdm1a, CoRest and NuRD complexes components following IP with Kdm1a antibody in tailfin uninjured or injured at 5 dpa. Dpa days post-amputation. N = 3 biological replicates.
