Genes affected

USP34 (HGNC:20066): (ubiquitin specific peptidase 34) Enables cysteine-type endopeptidase activity and thiol-dependent deubiquitinase. Involved in positive regulation of canonical Wnt signaling pathway and protein K48-linked deubiquitination. Predicted to be active in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

AHSA2P (HGNC:20437): (activator of HSP90 ATPase homolog 2, pseudogene) Predicted to enable ATPase activator activity. Predicted to be involved in positive regulation of ATPase activity and protein folding. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]
