Function
HRD3 is a component of the endoplasmic reticulum (ER) quality control system known as ER-associated degradation (ERAD). It plays a crucial role in ubiquitin-dependent degradation of misfolded ER proteins. HRD3 acts as an ERAD substrate-recruiting factor, recognizing misfolded proteins and directing them to the HRD1 E3 ubiquitin ligase complex for degradation.
