SPHK1 Antibody (N-term P74) Blocking Peptide

Synthetic peptide

Product Information
Primary Accession Q9NYA1
Clone Names 80208135
Peptide ID 80208135
Additional Information
Gene ID 8877
Other Names Sphingosine kinase 1, SK 1, SPK 1, SPHK1, SPHK, SPK
Target/Specificity The synthetic peptide sequence used to generate the antibody AP7237d was selected from the N-term region of human SPHK1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
Format Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.
PrecautionsThis product is for research use only. Not for use in diagnostic or therapeutic procedures.
Protein Information
Name SPHK1
Synonyms SPHK, SPK
Function Catalyzes the phosphorylation of sphingosine to form sphingosine 1-phosphate (SPP), a lipid mediator with both intra- and extracellular functions. Also acts on D-erythro-sphingosine and to a lesser extent sphinganine, but not other lipids, such as D,L-threo-dihydrosphingosine, N,N-dimethylsphingosine, diacylglycerol, ceramide, or phosphatidylinositol.
Cellular Location Cytoplasm. Nucleus. Cell membrane. Note=Translocated from the cytoplasm to the plasma membrane in a CIB1-dependent manner
Tissue Location Widely expressed with highest levels in adult liver, kidney, heart and skeletal muscle

Sphingosine Kinase (SphK) catalyzes the phosphorylation of the lipid sphingosine, creating the bioactive lipid sphingosine-1-phosphate (S1P). S1P subsequently signals through cell surface G protein-coupled receptors, as well as intracellularly, to modulate cell proliferation, survival, motility and differentiation. SphK is an important signaling enzyme which is activated by diverse agents, including growth factors that signal through receptor tyrosine kinases, agents activating G protein-coupled receptors, and immunoglobulin receptors. Two SphK isotypes, SphK-1 and SphK-2, have been cloned, and both isotypes are ubiquitously expressed. SphK-1 has been shown to mediate cell growth, prevention of apoptosis, and cellular transformation, and is upregulated in a variety of human tumors. In contrast, SphK-2 increases apoptosis, and may be responsible for phosphorylating and activating the immunosuppressive drug FTY720.
