Genes affected

PDIA3 (HGNC:4606): (protein disulfide isomerase family A member 3) This gene encodes a protein of the endoplasmic reticulum that interacts with lectin chaperones calreticulin and calnexin to modulate folding of newly synthesized glycoproteins. The protein was once thought to be a phospholipase; however, it has been demonstrated that the protein actually has protein disulfide isomerase activity. It is thought that complexes of lectins and this protein mediate protein folding by promoting formation of disulfide bonds in their glycoprotein substrates. This protein also functions as a molecular chaperone that prevents the formation of protein aggregates. [provided by RefSeq, Dec 2016]

ELL3 (HGNC:23113): (elongation factor for RNA polymerase II 3) Predicted to enable cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription, DNA-templated and transcription by RNA polymerase II. Located in several cellular components, including chromosome; cytosol; and nuclear lumen. Part of transcription elongation factor complex. [provided by Alliance of Genome Resources, Apr 2022]
