Genes affected

RHBDF1 (HGNC:20561): (rhomboid 5 homolog 1) Predicted to enable growth factor binding activity and serine-type endopeptidase activity. Involved in several processes, including negative regulation of protein secretion; regulation of epidermal growth factor receptor signaling pathway; and regulation of proteasomal protein catabolic process. Located in Golgi membrane and endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]
