CAB39 Antibody

Code CSB-PA640939LA01HU
Size US$299
  • Immunofluorescence staining of Hela cells with CSB-PA640939LA01HU at 1:100, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

Component of a complex that binds and activates STK11/LKB1. In the complex, required to stabilize the interaction between CAB39/MO25 (CAB39/MO25alpha or CAB39L/MO25beta) and STK11/LKB1.
Gene References into Functions
  1. miR-451 directly targets CAB39 and negatively regulates its expression and inhibition of CAB39 contributes to the promoted cell viability and invasion PMID: 28197410
  2. These data provide molecular understanding of the mechanism by which MO25 isoforms regulates the activity of STE20 family protein kinases. PMID: 23296203
  3. Authors conclude that miR-451 represses glioma in vitro and in vivo, likely through targeting CAB39 directly and inhibiting the PI3K/AKT pathway indirectly. PMID: 22179124
  4. MO25 is a master regulator of SPAK/OSR1 and MST3/MST4/YSK1 protein kinases. PMID: 21423148
  5. study describes structure of the core heterotrimeric LKB1-STRADalpha-MO25alpha complex, revealing an unusual allosteric mechanism of LKB1 activation; structure also reveals how mutations in Peutz-Jeghers syndrome & sporadic cancers impair LKB1 function PMID: 19892943
  6. STRADalpha.MO25alpha complexes containing LKB1 variants were equally effective at phosphorylating and activating AMPK, BRSK1, and BRSK2 PMID: 18854318
  7. These data define a brush border induction pathway downstream of the Lkb1/Strad/Mo25 polarization complex, yet separate from other polarity events. PMID: 19386264
  8. ATP and MO25alpha cooperate to maintain STRADalpha in an "active" closed conformation required for LKB1 activation. PMID: 19513107
  9. plays very important oncogenic roles in hepatocellular carcinoma pathogenesis and progression by activating the ERK signaling pathway PMID: 28605041
