Ripk1 - receptor (TNFRSF)-interacting serine-threonine kinase 1

Enables protein homodimerization activity and protein serine/threonine kinase activity. Involved in several processes, including necroptotic signaling pathway; negative regulation of cardiac muscle cell proliferation; and regulation of signal transduction. Acts upstream of or within several processes, including positive regulation of I-kappaB kinase/NF-kappaB signaling; regulation of extrinsic apoptotic signaling pathway; and ripoptosome assembly involved in necroptotic process. Predicted to be located in several cellular components, including cytosol; membrane raft; and mitochondrion. Predicted to be part of death-inducing signaling complex; receptor complex; and ripoptosome. Is expressed in several structures, including central nervous system; heart; liver; lung; and tail. Human ortholog(s) of this gene implicated in immunodeficiency 57. Orthologous to human RIPK1 (receptor interacting serine/threonine kinase 1). [provided by Alliance of Genome Resources, Apr 2022]
