Sphingosine Kinase 1/SPHK1 Antibody

Western Blot: Sphingosine Kinase 1/SPHK1 Antibody [NBP3-23415] - Western blot image of recombinant his-tagged human Sphingosine Kinase 1/SPHK1 protein that was phosphorylated with ERK-2. Blots were probed with anti-Sphingosine Kinase 1/SPHK1 (Central Region) (NBP3-23415; lanes 1-3) and anti-Sphingosine Kinase 1/SPHK1 (Ser-225) (NBP3-23421; lanes 4-6). Both antibodies were used in the presence of no peptide (lanes 1 & 4), phospho-Sphingosine Kinase 1/SPHK1 (Ser-225) peptide (lanes 2 & 5), or unphosphorylated Sphingosine Kinase 1/SPHK1 (Ser-225) peptide (lanes 3 & 6).

Western Blot: Sphingosine Kinase 1/SPHK1 Antibody [NBP3-23415] - Western blot of HeLa stimulated with calyculin A (lanes 1-4). The blots were untreated (lane 1 & 3) or treated with lambda phosphatase (lane 2 & 4), then probed with anti-Sphingosine Kinase 1/SPHK1 (Central region) NBP3-23415 (lanes 1 & 2) or anti-Sphingosine Kinase 1/SPHK1 (Ser-225) NBP3-23421 (lanes 3 & 4).

Sphingosine Kinase 1/SPHK1 Antibody Summary

• Description: Stable for at least 1 year at -20°C.
• Immunogen: Sphingosine Kinase 1/SPHK1 synthetic peptide (coupled to carrier protein) corresponding to an unphosphorylated sequence of amino acids surrounding serine 225 in the central region of human Sphingosine Kinase 1/SPHK1. This sequence has 4 amino acid differences from mouse and 5 from rat Sphingosine Kinase 1/SPHK1, and is not homologous to sequences in Sphingosine Kinase 2/SPHK2. [UniProt# Q9NYA1]
• Specificity: The antibody detects a 47 kDa full-length recombinant human Sphingosine Kinase 1/SPHK1 protein.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: SPHK1

Background

Sphingosine-1-phosphate (SPP) is a novel lipid messenger with both intracellular and extracellular functions. Intracellularly, it regulates proliferation and survival, and extracellularly, it is a ligand for EDG1 (MIM 601974). Various stimuli increase cellular levels of SPP by activation of sphingosine kinase (SPHK), the enzyme that catalyzes the phosphorylation of sphingosine. Competitive inhibitors of SPHK block formation of SPP and selectively inhibit cellular proliferation induced by a variety of factors, including platelet-derived growth factor (e.g., MIM 173430) and serum.[supplied by OMIM]
