KLHL20 and its role in cell homeostasis: A new perspective and therapeutic potential.

Ubiquitin ligases are proteins with the ability to trigger non-degradative signaling or proteasomal destruction by attracting substrates and facilitating ubiquitin transfer onto target proteins. Over the years, there has been a continuous discovery of new ubiquitin ligases, and Kelch-like protein 20 (KLHL20) is one of the most recent discoveries that have several biological roles which include its role in ubiquitin ligase activities. KLHL20 binds as a substrate component of ubiquitin ligase Cullin3 (Cul3).
