Product information

PLCγ2 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). PLCγ2 is expressed primarily in immune cells and acts downstream of soluble tyrosine kinases recruited by T and B cell receptors to modulate acute responses.1,2

Protein is > 92% pure as determined by densitometry of the final sample submitted to SDS-PAGE and stained with Coomassie blue (Fig. 1). PLCγ2 was heterologously expressed in High 5 insect cells 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-Gln-Ala tripeptide at the N-terminus followed by residues 1-1195 of human PLCγ2. Purified PLCγ2 lacks 70 residues from its C-terminus that are not conserved. This truncation improves purity and solubility without affecting lipase activity.
