I am asking this question because it is hard to prove non-existence (of better data):
I am searching for a good RNA-binding motif database that is as up-dated as possible and covers motifs for as many proteins (RBPs) as possible.
After some research I found that ATtRACT looks like the best source. According to my analysis, it covers 77 proteins from RNAcompete- data and 27 proteins from SELEX-data.
Background: I am not interested in a single protein, I need as many different proteins as possible. I am asking this question to make sure I don't have to repeat my analysis, if reviewers say my sources are too old.
