D-ribo-Phytosphingosine-1-Phosphate is suitable for use as a ligand for sphingosine-1-phosphate receptor 4 in competition binding studies. It is also suitable for use as an internal standard for the quantification of spingoid bases in maize samples using mass spectrometry and reverse phase high-performance liquid chromatography
ChEBI: Phytosphingosine 1-phosphate is a phosphosphingolipid that is phytosphingosine bearing a phospho group at position 1. It has a role as a Saccharomyces cerevisiae metabolite. It is functionally related to a phytosphingosine. It is a conjugate acid of a phytosphingosine 1-phosphate(1-).
D-ribo-Phytosphingosine-1-Phosphate (phS1P) plays a key role in cell growth. In yeast, it coordinates response to he at stress.
