General rule information [?]

Accession PRU00204
Dates 12-DEC-2003 (Created)
28-NOV-2019 (Last updated, Version 8)
Data class Domain
Predictors PROSITE; PS50104; TIR
Name TIR
Function The TIR domain has been defined as a scaffold that promotes assembly of signaling complexes via protein-protein interactions. However, the scaffolding function may be a a recent adaptation. The primordial function of the TIR domain is a self-association-dependent nicotinamide dinucleotide (NAD(+))-cleaving enzyme (NADase) activity that cleaves NAD(+) into nicotinamide (Nam) and ADP-ribose (ADPR), cyclic ADPR (cADPR) or variant cADPR (v-cADPR), with catalytic cleavage executed by a conserved glutamic acid.

Description [?]

case <FTTag:act_site>
+ AltName: Full=Probable NAD(+) hydrolase; EC;

Comments [?]

Catalytic activity RHEA:16301: H2O + NAD(+) = ADP-D-ribose + H(+) + nicotinamide
PhysiologicalDirection=left-to-right (RHEA:16302)
Domain The TIR domain mediates NAD(+) hydrolase (NADase) activity. Self-association of TIR domains is required for NADase activity.
