Description

Peptide sequence: human sphingosine kinase 1 (SPHK 1) amino acids 264-274 (DLESEKYRRLG) · To be used in conjunction with Cayman’s Sphingosine Kinase 1 polyclonal antibody (Catalog No. 10006822) to block protein-antibody complex formation during immunochemical analysis of SPHK 1 protein. · SPHK 1 catalyzes the phosphorylation of sphingosine to sphingosine-1-phosphate. This reaction plays an important role in determining cell proliferation versus cell death.1,2 SPHK 1 is found in a wide variety of tissues and cell types including kidney, liver, spleen, heart, platelets, and human tumors. On a cellular level, it is found in the cytosolic and membrane fractions.3 Based on the amino acid sequence, this protein has a molecular weight of approximately 43 kDa. The observed band at 50 kDa may be explained by some reported post translational modifications.4
