I am new to biology and I have a question about phosphorylation site and protein kinase. I know that each protein kinase could have 1 or more than 1 phosphorylation sites. For example, mTOR has s2448, T2446 and so far. Is there any other protein kinase that would have a phosphorylation site named as s2448 or T2446 ad so far. I mean are phosphorylation sites' names unique or there are some protein kinases which have the same phosphorylation sites' names?
