Two distinct caveolin-1 domains mediate the functional interaction of caveolin-1 with protein kinase A.
Numerous components of the cAMP-based signaling cascade, namely G-proteins and G- protein coupled receptors, adenylyl cyclase, and protein kinase A (PKA) have been localized to caveolae and shown to be regulated by the caveolar marker proteins, the caveolins. In order to gain mechanistic insights into these processes in vivo, we have assessed the functional interaction of caveolin-1 (Cav-1) wit...
متن کاملProtein kinase A- and protein kinase C-regulated interaction of plectin with lamin B and vimentin.
Solid-phase binding assays with protein species purified from cultured rat glioma C6 cells and Ehrlich ascites revealed that plectin bound specifically to lamin B but not to lamins A and C. Lamin B interaction was significantly decreased upon in vitro phosphorylation of either lamin B or plectin with protein kinase A or C. In contrast, phosphorylation of plectin with kinase A increased its bind...
متن کاملMechanism of A-kinase-anchoring protein 79 (AKAP79) and protein kinase C interaction.
The A-kinase-anchoring protein AKAP79 co-ordinates the location of cAMP-dependent protein kinase, phosphatase 2B (PP2B/calcineurin) and protein kinase C (PKC) at postsynaptic sites in neurons. In this report we focus on the mechanism of interaction between AKAP79 and PKC. We show that neither lipid activators nor kinase activation are required for association with AKAP79. The anchoring protein ...
متن کاملActivation of protein kinase C with cardiolipin-containing liposomes in relation to membrane-protein interaction.
Many cytoplasmic proteins, including Ca2+- and phospholipid-dependent protein kinase (protein kinase C) of polymorphonuclear leukocytes (PMNs) associate in Ca2+-dependent manner with phospholipid liposomes containing cardiolipin (CL), as in the case of phosphatidylserine (PS)-containing liposomes. A crude protein kinase C fraction was purified by association of the enzyme with CL-containing lip...
متن کاملNonsteroidal antiestrogen suppresses protein kinase C--its inhibitory effect on interaction of substrate protein with membrane.
The mechanism by which nonsteroidal antiestrogen inhibits Ca(2+)- and phospholipid-dependent protein kinase (PKC) activity was investigated. Antiestrogenic agents, clomiphene and tamoxifen, inhibited the PKC-dependent phosphorylation of histone and r-annexin I in a dose-dependent manner. Ki values for the agents were different for two substrate proteins. The inhibitory action of the agents depe...
