A good enough up-to-date phosphorylation database?

Question

[Elendol]

Hi,

There are a lot of phosphorylation data bases out there, I would like to know which one is considered a gold standard, or at best good enough and up-to-date (as much as possible) data base of experimentally validated phosphoylation sites to use as reference against simple motif predictions. I'm working with mammalian proteins so a coverage of multiple species would be a bonus.

Check out PhosphoELM.

I did, but the data base didn't receive any update since 2010 apparently.
