Genes affected

SERINC1 (HGNC:13464): (serine incorporator 1) Predicted to enable protein-macromolecule adaptor activity. Predicted to be involved in several processes, including phosphatidylserine metabolic process; positive regulation of CDP-diacylglycerol-serine O-phosphatidyltransferase activity; and positive regulation of serine C-palmitoyltransferase activity. Predicted to be located in endoplasmic reticulum membrane and plasma membrane. Predicted to be active in membrane. [provided by Alliance of Genome Resources, Apr 2022]
