PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	N-terminal pleckstrin homology (PH) domain (essential for CERK activity, binding to phosphatidylinositol phosphates and localisation to the golgi and plasma membranes) (Don 2009)
	a calmodulin binding motif

text	PH domain is essential for localisation to the golgi and plasma membranes (Don 2009)

basic FUNCTION	playing a role in arachidonic acid release and production of eicosanoids
	in mast cell degranulation CERK acts downstream of CALM1, similar to CALM1-dependent protein kinase II, which had been assumed to be the main target of CALM1 in mast cells
