CNF1 increases phosphorylation of HACE1 on Ser-385. (a) Fragmentation spectra of the DS(p)TEITSILLK(+2) peptide showing that Ser-385 is phosphorylated. (b) Protein lysates from HUVECs transfected with HA-HACE1(WT) and treated with CNF1 at 10−9 M for 24 hours were treated or not with λ-phosphatase (λ-PPase) and analyzed by immunoblot (IB) using the indicated antibodies. IB: actin is used as a loading control. (c) Graph showing levels of pSer-385HACE1 relative to HACE1 total protein levels quantified by densitometry from the IB analysis. Data correspond to the mean ± SD of >3 biological replicates. p value was determined by one-sample t-test. (d) Protein lysates from HUVECs transfected with HA-HACE1(WT) or HA-HACE1(S385A), treated with CNF1 at 10−9 M for 24 hours and analyzed by IB. (e) Protein lysates from HUVECs transfected with HA-HACE1(WT), treated with CNF1 at 10−9 M for the indicated times, and analyzed by IB. (f) Protein lysates from HUVECs treated with CNF1 at 10−9 M for 24 hours. IBs in (b,d,e,f) are cropped from the full-length blots shown in Supplemental Figure S9.
