The mouse ortholog of NRK encodes Nik Related Kinase kinase required for JNK activation. The encoded protein may be involved in the induction of actin polymerization in late embryogenesis. NRK (Nik Related Kinase) is a Protein Coding gene. Diseases associated with NRK include Hypermobility Syndrome and Sotos Syndrome 1. Among its related pathways are TNF signaling (REACTOME) and NAD metabolism.
