Ca2+-dependent binding of cytosolic components to insulin-secretory granules results in Ca2+-dependent protein phosphorylation.
1. Incubation of a rat islet cell tumour homogenate with [gamma-32P]ATP resulted in the Ca2+-dependent phosphorylation of 100000-, 57000-, 29000-, 26000- and 14000-Mr proteins. The Ca2+ concentration required was in the low-microM range. 2. Isolated insulin granules did not exhibit Ca2+-dependent protein phosphorylation, whereas a soluble protein fraction showed the Ca2+-dependent phosphorylati...
متن کاملIdentification of the major mannose-binding proteins from chicken egg yolk and chicken serum as immunoglobulins.
Chicken egg yolk contains a mannose-binding protein that could be purified with a modification of the procedure of affinity chromatography and gel filtration used for chicken serum mannose-binding protein. The yolk protein was indistinguishable from the serum protein with respect to apparent molecular masses (169 +/- 7 kDa), subunits (74 kDa and 27 kDa, in approximately 1:1 ratio) produced afte...
متن کاملIdentification of Amino Acids Involve in Indium Binding To Serum Human Apo-Transferrin
Indium is a heavy metal belonging to group IIIa. It is used as a radioimaging and chemotherapeutic agent in diagnosis and also in the treatment of cancers. It is believed that indium may interfere with iron metabolism and reduce cell growth in cancer tissue. The present report was established to study the binding of iron and indium to apo-transferrin (apo-tf) and to identify amino acids involv...
متن کاملBinding of Regulatory Subunits of Cyclic AMP-Dependent Protein Kinase to Cyclic CMP Agarose
The bacterial adenylyl cyclase toxins CyaA from Bordetella pertussis and edema factor from Bacillus anthracis as well as soluble guanylyl cyclase α(1)β(1) synthesize the cyclic pyrimidine nucleotide cCMP. These data raise the question to which effector proteins cCMP binds. Recently, we reported that cCMP activates the regulatory subunits RIα and RIIα of cAMP-dependent protein kinase. In this st...
متن کاملGelsolin, a Ca2+-dependent actin-binding protein in a hamster insulin-secreting cell line.
Using a gel overlay technique we have previously described a 90,000-mol wt actin-binding protein in a number of hormone-secreting tissues and tentatively identified this protein as gelsolin. Gelsolin is a protein that cuts or solates cross-linked actin filaments and can also serve as a nucleating site for actin polymerization. The objective of this study was to isolate this protein from a hamst...
