The function of SVIP (small VCP interacting protein, Ensembl gene identifier ENSG00000198168) is as follows. Negative regulator of the ER-associated degradation pathway (ERAD) of misfolded proteins. It competes with AMFR/gp78 for binding VCP/p97, and inhibits AMFR/gp78-VCP/p97 complex formation that is required for degradation of ERAD substrates (PubMed:17872946). Involved in the regulation of adrenal cortisol and dehydroepiandrosterone (DHEA) biosynthesis (PubMed:35042898). {ECO:0000269|PubMed:17872946, ECO:0000269|PubMed:35042898}.
