Whole proteome analysis of human tankyrase knockout cells reveals targets of tankyrase-mediated degradation

Abstract

Tankyrase 1 and 2 are poly(ADP-ribose) polymerases that mark proteins for degradation, but there is a current lack of knowledge about their distinct functions and substrates. Here, the authors elucidate the cellular roles and substrates of these polymerases using comparative functional and proteomics analyses of tankyrase knockout cell lines.
