Phospholipase A2 (PLA2) is the enzyme regulating the release of arachidonic acid in most cell types. A high molecular mass, 85-kDa soluble form of PLA2 (cPLA2) has recently been identified, the(More)
Stimulation of the acetylcholine muscarinic m2 receptor (m2R) expressed in Rat 1a fibroblasts results in the activation of the cytoplasmic mitogen-activated protein kinase (MAPK). Concomitant with(More)
Gq is the heterotrimeric guanine nucleotide-binding protein that activates the beta isoforms of phosphatidyl-inositol-specific phospholipase C (PI-PLC). The Gq alpha-subunit polypeptide (alpha qa)(More)
Engagement of the B-cell antigen receptor complex induces immediate activation of receptor-associated Src family tyrosine kinases including p55blk, p59fyn, p53/56lyn, and perhaps p56lck, and this(More)
The 85-kDa cytoplasmic phospholipase A2 (cPLA2) is the major hormone and growth factor-regulated enzyme that catalyzes release of arachidonic acid in mammalian cells. Activation of cPLA2 requires(More)
