Background

STK25 (Serine/threonine protein kinase 25, YSK, SOK1) belongs to the germinal center kinase III (GCKII) subfamily of sterile-20 (STE20) protein kinases (1). STK25 is highly conserved across metazoans, and is reported to be involved in various core cellular processes, including cell migration (2,3) and metabolism (4,5). Along with the closely related MST3 and MST4 kinases, STK25 has been identified as a component of the striatin-interacting phosphatase and kinase (STRIPAK) complex (6). Its role in this regard is one of the mechanisms by which it has been reported to regulate the Hippo signaling pathway (7,8). A defined role for STK25 in lipid metabolism (9) has led some to consider targeting STK25 for the treatment of lipid-related metabolic diseases (10), including non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) (11,12).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Immunoprecipitation Image 1: STK25 (E7T2F) Rabbit mAb Expand Image
Immunoprecipitation of STK25 protein from Hep G2 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is STK25 (E7T2F) Rabbit mAb. Western blot analysis was performed using STK25 (E7T2F) Rabbit mAb. Mouse Anti-rabbit IgG (Conformation Specific) (L27A9) mAb (HRP Conjugate) #5127 was used as a secondary antibody. *The antibody also detects 40 kDa and 180 kDa proteins of unknown identity after immunoprecipitation.
