Genes affected
WDR83 (HGNC:32672): (WD repeat domain 83) This gene encodes a member of the WD-40 protein family. The protein is proposed to function as a molecular scaffold for various multimeric protein complexes. The protein associates with several components of the extracellular signal-regulated kinase (ERK) pathway, and promotes ERK activity in response to serum or other signals. The protein also interacts with egl nine homolog 3 (EGLN3, also known as PHD3) and regulates expression of hypoxia-inducible factor 1, and has been purified as part of the spliceosome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
WDR83OS (HGNC:30203): (WD repeat domain 83 opposite strand) Enables protein folding chaperone. Involved in protein insertion into ER membrane. Is integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]
