Phospho-SK1 (Ser-225) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding serine 225 in human SK1. This sequence has 4 amino acid differences from mouse and 5 from rat SK1, and is not homologous to sequences in SK2. The conserved site in rat and mouse SK1 is at serine 224.

Product Specific Information

This antibody was cross-adsorbed to non-specific phosphoserine and unphosphorylated SK1 (Ser-225) peptide before affinity purification using phospho-SK1 (Ser-225) peptide. The purified antibody detects a 47 kDa* full-length recombinant human SK1 protein phosphorylated with ERK2.

Target Information

SPHK1, along with SPHK2, catalyzes the phosphorylation of sphingosine producing the signaling molecule sphingosine-1-phosphate (S1P). S1P signals through G-protein coupled receptors and controls diverse cellular processes. Inhibitors of SPHKs are viewed as potential therapeutics for the treatment of cancer. SPHK1 catalyzes the phosphorylation of sphingosine to sphingosine 1 phosphate (S1P), an important signaling molecule with intra- and extracellular functions. Inside the cell S1P acts as a signaling molecule like other sphingolipid metabolites like ceramide and sphingosine. S1P has been implicated in regulating cell differentiation, calcium mobilization from intracellular stores, and apoptosis. The cell surface receptors for S1P are the EDG family of G protein-coupled receptors (S1P Receptors).
