Invitrogen™ Human TANK (aa 7-90) Control Fragment Recombinant Protein

TANK was initially identified as a novel TRAF-interacting protein that regulated TRAF-mediated signal transduction. Specifically, ligand binding by surface receptors in the tumor necrosis factor (TNF) receptor and Toll/interleukin-1 (IL-1) receptor families lead to the formation of a TRAF/TANK complex that mediates the activation of the transcription factor NF-kappa-B. This activation of NF-kappa-B occurs through an association with the kinases IKK-iota and TBK1. More recently, it was shown that these proteins can then form a complex with NEMO, a protein that regulates the activity of the Ikappa-B complex. This suggests that in addition to the possibility that TBK1 and IKK-iota activate the IKKs, the association with the IKK complex may help these kinases modulate other functions, such as the transactivation potential of NF-kappa-B proteins. At least two isoforms of TANK are known to exist.
