Genes affected

RFNG (HGNC:9974): (RFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase) Predicted to enable O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase activity. Predicted to be involved in regulation of Notch signaling pathway. Predicted to act upstream of or within positive regulation of Notch signaling pathway and positive regulation of protein binding activity. Predicted to be integral component of Golgi membrane.

GPS1 (HGNC:4549): (G protein pathway suppressor 1) This gene is known to suppress G-protein and mitogen-activated signal transduction in mammalian cells. The encoded protein shares significant similarity with Arabidopsis FUS6, which is a regulator of light-mediated signal transduction in plant cells. [provided by RefSeq, Mar 2016]
