Genes affected

SERPINA12 (HGNC:18359): (serpin family A member 12) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to act upstream of or within negative regulation of gluconeogenesis; positive regulation of signal transduction; and regulation of lipid metabolic process. Predicted to be located in plasma membrane. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]
