Overview
ASK1 a protein kinase of the STE11 family. Phosphorylates and activates two different subgroups of MAP kinase kinases, MKK4/SEK1 and MKK3/MKK6, which in turn activate stress-activated protein kinase (JNK) and p38 subgroups of MAP kinases, respectively. Overexpression induces apoptotic cell death. Note: This description may include information from UniProtKB.
