CTTN and breast cancer: Although no phosphorylation was detected on S113 or S282 in these experiments, phosphoproteome analyses from other studies have previously shown that Cortactin is phosphorylated in vivo on S113, S150 and/or S282: S113 phosphorylation was detected in prostate cancer cells (Chen et al., 2010), mouse brain (Wiśniewski et al., 2010) and breast cancers (Mertins et al., 2016).
