Our Anti-Munc18-1 (Ser241) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse and rat Munc18-1 (Ser241) and is antigen affinity purified from pooled serum. It is great for use in WB, IHC.

Western blot of mouse hippocampal lysate showing specific immunolabeling of the ~65 kDa Munc18-1 protein phosphorylated at Ser241 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 min).

Product Details

Munc18-1 (Ser241)
Munc-18 (mammalian homologue of Unc-18) is a protein that is thought to be involved in regulating exocytosis due, at least in part, to it ability to bind syntaxin (Ciufo et al., 2005). Munc18-1 is a neuron-specific member of the Sec1/Munc18 protein family that binds to syntaxin1A and is thought to stabilize the complex (Liu et al., 2004). The function of Munc18-1 is thought to be regulated by phosphorylation.
