Genes affected

JKAMP (HGNC:20184): (JNK1/MAPK8 associated membrane protein) Enables ubiquitin protein ligase binding activity. Involved in ubiquitin-dependent ERAD pathway. Predicted to be located in endoplasmic reticulum membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

L3HYPDH (HGNC:20488): (trans-L-3-hydroxyproline dehydratase) The protein encoded by this gene is a dehydratase that converts trans-3-hydroxy-L-proline to delta(1)-pyrroline-2-carboxylate. This enzyme may function to degrade dietary proteins that contain trans-3-hydroxy-L-proline as well as other proteins such as collagen IV. The encoded protein can be converted to an epimerase by changing a threonine to a cysteine at a catalytic site. [provided by RefSeq, Sep 2016]

ENSG00000258782 (HGNC:):
