Rather than degradation, poly-K63 ubiquitin chains act as scaffolds that bind proteins that have a poly-K63 ubiquitin-binding domain

#XL - T Zoology

Poly-K63 ubiquitin-binding domain containing proteins:

Protein kinase TAK1

NEMO subunit of the I-κB kinase

#XL - T Zoology

Poly-K63 ubiquitin chain brings TAK1 kinase and β subunit of I-κB

kinase, into close proximity so that TAK1 can phosphorylate and activate I-κB kinase
