Biochem/physiol Actions

Recombinant human YSK4 (MAP3K19) (941-end) was expressed by Baculovirus in Sf9 insect cells using an N-terminal GST tag. YSK4 (MAP3K19, RCK) belongs to STE Ser/Thr protein kinase family and STE20 subfamily. The YSK4 gene is conserved in chimpanzee, Rhesus monkey, dog, cow, mouse, and rat (1). The important paralog is MAP3K1 gene. The RCK ligand-binding domains form an octameric gating ring (2) in the large-conductance Ca2+-activated K+ channels (3). The YSK4 kinase function has not been made clearly yet.

Reconstitution

Formulated in 50mM Tris-HCl, pH 7.5, 150mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25 mM DTT, 0.1 mM PMSF, with 25% glycerol.

Storage and Stability
