Human Gene EDEM2 (uc002xbo.2) Description and Page Index
  Description: Homo sapiens ER degradation enhancer, mannosidase alpha-like 2 (EDEM2), transcript variant 1, mRNA.
RefSeq Summary (NM_018217): In the endoplasmic reticulum (ER), misfolded proteins are retrotranslocated to the cytosol and degraded by the proteasome in a process known as ER-associated degradation (ERAD). EDEM2 belongs to a family of proteins involved in ERAD of glycoproteins (Mast et al., 2005 [PubMed 15537790]).[supplied by OMIM, Mar 2008].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=ER degradation-enhancing alpha-mannosidase-like 2; Flags: Precursor;
FUNCTION: Involved in endoplasmic reticulum-associated degradation (ERAD) that targets misfolded glycoproteins for degradation in an N-glycan-dependent manner. It lacks mannosidase activity. Extracts misfolded glycoproteins, but not glycoproteins undergoing productive folding, from the calnexin cycle.
SUBCELLULAR LOCATION: Secreted. Endoplasmic reticulum lumen.
TISSUE SPECIFICITY: Expressed ubiquitously in all tissues tested with slightly higher levels detected in small intestine and peripheral blood leukocytes and weakest levels in brain and skeletal muscle.
INDUCTION: Up-regulated by the unfolded protein response (UPR) via the XBP1 transcription factor.
PTM: Glycosylated.
SIMILARITY: Belongs to the glycosyl hydrolase 47 family.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on Q9BV94
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
