WWP2 Overall

Introduction

WWP2 is a type of ubiquitin protein ligase. More specifically, it is a member of the Homologous to the E6-AP Carboxyl Terminus (HECT) E3 Ligases class which accept a ubiquitin molecule from an enzyme upstream in the ubiquitination pathway and transfer the ubiquitin to a Lysine residue in the target signaling molecule or transcription factor. The thioester bond formation between an active site Cystine on HECT E3 Ligases and ubiquitin differentiates this family of enzymes from the more abundant RING family of ubiquitin ligases which mediate ubiquitin transfer through non-covalent interactions. Within HECT E3 Ligases, WWP2 falls into the NEDD4 family. NEDD4 E3 Ligases consist of an N-terminal C2 Domain, between 2-4 WW domains, and a C-terminal HECT domain.
