Genes affected

BRSK2 (HGNC:11405): (BR serine/threonine kinase 2) Enables several functions, including ATP binding activity; ATPase binding activity; and protein kinase activity. Involved in several processes, including cellular protein metabolic process; intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress; and regulation of insulin secretion involved in cellular response to glucose stimulus. Located in centrosome and endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]
