Als2Cr2 Antibody / STRADB

Als2Cr2, also called STE20-related kinase adapter protein beta (STRAD beta) and ILPIP, is a serine/threonine protein kinase encoded by the STRADB gene, discovered as an XIAP interacting protein. It is a mediator of the XIAP/TAK1 activation of the JNK1 pathway, an apoptosis inhibition mechanism independent of XIAP inhibition of caspases. Alone, it only moderately activates JNKs, but its interaction with XIAP/TAK1 induces a much stronger activation of JNK1, protecting against Caspase 1- or Fas-induced apoptosis.
