Recombinant human RIPK2(GenBank Accession No. NM_003821), (a.a. 1-299) with N-terminal Gst-tag,MW=59 kDa, expressed in an baculovirusinfected Sf9 cell expression system.
Host cell line: Sf9 cells
Specific activity: 20 pmol/min/ug
Background
RIPK2 (RIP2; RICK) is a death domain-containing protein kinase encoding a predicted 540-amino acid protein which contains an N-terminal serine/threonine kinase catalytic domain and a C-terminal caspase activation and recruitment domain. RIPK2 is thought to regulate apoptosis induced by the FAS receptor pathway (1). RIPK2 has been shown to specifically interact with the CARD of ICE/caspase-1 and this interaction correlates with the processing of pro-caspase-1 and the formation of the active caspase-1 p20 (2).
