Our Anti-MerTK (Tyr749/753/754) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat MerTK Tyr749/753/754 and is antigen affinity purified from pooled serum. It is great for use in WB.

Western blot of HEK293 lysate showing specific immunolabeling of the ~160 kDa MerTK phosphorylated at Tyr749/753/754 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 60 minutes).

Target

MerTK Tyr749/753/754

Target Description

Along with Tyro-3 and Axl, Mer is a member of the TAM family of receptor tyrosine kinases (RTKs). The TAM family of RTKs regulates cell proliferation/survival, cell adhesion and migration, and blood clot stabilization processes, along with the regulation of inflammatory cytokine release (Linger et al, 2008). Additionally, the TAM family has been linked to coagulopathy and cancer when altered experimentally or genetically (Linger et al, 2008). Tri-phosphorylation of MerTK at tyr749, tyr753 and tyr754 has been identified as a key target in platelet aggregation for developing a new anti-platelet drug that decreases bleeding complications, which are current side effects of similar drugs on the market today (Zhang et al, 2013). MerTK is also seen as a therapeutic target for treating lymphoblastic leukemias, melanoma, breast, lung, colon, liver, gastric, kidney, ovarian, uterine and brain cancers (Graham et al, 1994). There has recently been increased interest in synthesizing novel ATP-competitive small molecule tyrosine kinase inhibitors to decrease tri-phosphorylation of MerTK at tyr749, tyr753, and tyr754 as a therapeutic target to treat AML (Lee-Sherick et al, 2013).

Species Reactivity

Human, Mouse, Rat

Expected Reactivity

Bovine, Canine, Chicken, Finch, Guinea Pig, Non-Human Primate

Antibody Registry ID

AB_2744537

Storage

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Physical State

Liquid

Production Notes

Prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho and non-phosphopeptide affinity columns.

Buffer

10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

Dilution Ranges

WB: 1:1000

Conjugate

Unconjugated

Specificity

Specific for the ~160 kDa MerTK protein phosphorylated at Tyr749/753/754. The immunolabeling is completely eliminated by treatment with λ-phosphatase. Due to post-translational modifications of the Mer protein, a significant shift in molecular weight is seen from the predicted molecular weight of 110 kDa. For optimal results immunoprecipitation is recommended due to the 91% homology of the related receptor tyrosine kinase, Axl, that runs at ~140 kDa.

Post Translational Modification Type

Phosphorylated

Post Translational Modification Residue
