Genes affected

ZDHHC2 (HGNC:18469): (zinc finger DHHC-type palmitoyltransferase 2) Enables protein homodimerization activity and protein-cysteine S-palmitoyltransferase activity. Involved in several processes, including peptidyl-L-cysteine S-palmitoylation; regulation of protein catabolic process; and regulation of protein localization to plasma membrane. Located in Golgi apparatus and endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]
