STXBP1 antibody (pSer515)

Catalog No. ABIN372671

Product Details anti-STXBP1 Antibody

Target: STXBP1 (Syntaxin Binding Protein 1 (STXBP1))

Binding Specificity: pSer515

Reactivity: Human, Mouse, Rat, Cow, Dog, Chicken, Xenopus laevis

Host: Rabbit

Clonality: Polyclonal

Conjugate: This STXBP1 antibody is un-conjugated

Application: Western Blotting (WB), Immunohistochemistry (Frozen Sections) (IHC (fro))

Specificity: This antibody recognizes ~65k Munc-18 protein phosphorylated at Ser515. Immunolabeling is blocked by the phosphopeptide used as antigen but not by the corresponding dephosphopeptide.

Purification: Sequential Chromatography on phospho- and dephosphopeptide affinity columns.

Immunogen: Phosphopeptide corresponding to amino acid residues surrounding the phospho- Ser515 of Munc-18.

Isotype: IgG

Target Details for STXBP1

Target: STXBP1 (Syntaxin Binding Protein 1 (STXBP1))

Alternative Name: STXBP1 / UNC18A (STXBP1 Products)

Background: 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 Munc-18 is thought to be regulated by PKC phosphorylation of Ser515 on the Munc-18 protein (Sassa et al., 1996).
