Anti-SNAP25 (Ser187) Antibody

Name: Anti-SNAP25 (Ser187) Antibody
Brand: PhosphoSolutions
SKU: p1558-187
Price: 456.0 USD
Availability: InStock

Our Anti-SNAP25 (Ser187) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse and rat SNAP25 (Ser187) and is antigen affinity purified from pooled serum. It is great for use in WB.

Western blot of rat hippocampal lysate showing specific immunolabeling of the ~25 kDa SNAP25 phosphorylated at Ser187 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (λ-Ptase , 400 units/100ul lysate for 30 minutes, RT).

Target

SNAP25 (Ser187)

Scientific Background

SNAP25 (Synaptosomal associated protein of 25 kDa) is a presynaptic plasma membrane protein that is widely distributed throughout the brain and involved in the regulation of neurotransmitter release. Decreased levels of SNAP25 have been found in the brains of patients with Down Syndrome and Alzheimer’s Disease (Greber et al.,1999). In addition, a significant reduction in the hippocampal expression of SNAP25 has also been found in patients with Schizophrenia (Fatemi et al., 2001). Increasing evidence suggests that SNAP-25 also modulates various ion channels, including voltage gated calcium channels (VGCCs) (Pozzi el al., 2008). Activation of PKC results in the phosphorylation of SNAP-25 on Ser-187 is believed to cause inhibition of VGCC (Pozzi el al., 2008). Since Ser-187 phosphorylation is transiently induced by neuronal activity, SNAP25 creates a negative feedback mechanism for controlling neuronal excitability (Pozzi el al., 2008).
