Product information

PLCδ1 is a calcium-dependent lipase that hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP2) to produce the second messengers, inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG). In addition to the calcium co-factor used to hydrolyze PIP2, PLCδ1 also binds several calcium ions through its C2 domain. These additional calcium ions anchor PLCδ1 to negatively charged membranes and account for the exquisite sensitivity of this PLC to fluctuation in calcium.1,2

Protein is > 93% pure as determined by densitometry of the final sample submitted to SDS-PAGE and stained with Coomassie blue (Fig. 1). PLCδ1 was heterologously expressed in E. coli as a histidine-tagged protein and purified by a combination of affinity, ion exchange, and gel exclusion chromatographies. The tag was removed prior to final purification leaving a Ser-Asn-Ala tripeptide at the N-terminus followed by residues 1-755 of human PLCδ1.
