RN193

RN193 is a type II kinase inhibitor with a human PAK1 IC₅₀ of 4.28 μM. RN193 functionally inhibits kinase activity of PAK1, PAK2, and PAK3, and engages with their kinase domains in live cells. RN193 induces thermal shifts in CLK1, GSK3B, ULK1, MELK, MAPK13, BRAF, and STK10, indicating binding and stabilization of these proteins. RN193 induces formation of PAK3:PAK2 heterodimers and displaces PAK2 homodimers in live cells. RN193 acts as a tool compound for studying group I PAK conformational states.

RN193 (2 h) potently and selectively binds to the truncated kinase domains of group I PAK1, PAK2, and PAK3 in 293T cells, with IC₅₀ values ranging from 0.14 to 0.16 μM^[1].
RN193 (2 h) inhibits the kinase activity of purified PAK1^M248-H545 with an IC₅₀ of 4.28 μM in an in vitro ADP-Glo assay^[1].
RN193 (2 h) induces the formation of PAK3:PAK2 heterodimers in live HEK293T cells with an IC₅₀ of 0.38 μM; it also disrupts PAK2:PAK2 homodimers with an IC₅₀ of 0.42 μM^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
