Genes affected
P3R3URF (HGNC:53451): (PIK3R3 upstream open reading frame) Predicted to enable 1-phosphatidylinositol-3-kinase regulator activity. Predicted to be involved in phosphatidylinositol phosphate biosynthetic process. Predicted to be part of phosphatidylinositol 3-kinase complex. [provided by Alliance of Genome Resources, Apr 2022]
TSPAN1 (HGNC:20657): (tetraspanin 1) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. [provided by RefSeq, Jul 2008]
