The function of ENSG00000134109 (EDEM1, ER degradation enhancing alpha-mannosidase like protein 1) is as follows. Extracts misfolded glycoproteins, but not glycoproteins undergoing productive folding, from the calnexin cycle. It is directly involved in endoplasmic reticulum-associated degradation (ERAD) and targets misfolded glycoproteins for degradation in an N-glycan- independent manner, probably by forming a complex with SEL1L. It has low mannosidase activity, catalyzing mannose trimming from Man8GlcNAc2 to Man7GlcNAc2. {ECO:0000269|PubMed:12610306, ECO:0000269|PubMed:19524542, ECO:0000269|PubMed:19934218, ECO:0000269|PubMed:25092655}.
