Genes affected

SERPINB3 (HGNC:10569): (serpin family B member 3) Enables cysteine-type endopeptidase inhibitor activity; protease binding activity; and virus receptor activity. Involved in several processes, including autocrine signaling; paracrine signaling; and regulation of cellular protein metabolic process. Located in cytoplasmic vesicle; extracellular exosome; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

SERPINB11 (HGNC:14221): (serpin family B member 11) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to be located in cytoplasm. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]
