E3 ubiquitin-protein ligase HECW1 (HECW1)

E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent degradation of DVL1. Also targets the mutant SOD1 protein involved in familial amyotrophic lateral sclerosis (FALS).

Forms cytotoxic aggregates with DVL1, SSR3 and mutant SOD1 that cause motor neuron death in FALS. .
