Abstract:
:Most fish protamines contain two phosphorylatable sites both of which incorporate phosphate in vivo. Here we show that in two protamines (salmine A1 and clupeine Y1) the site more distant from the N-terminus (residues 20-21) is unaffected by cAMP-dependent protein kinase while it represents the main target for protein kinase C. Such a phosphorylation is typically independent of Ca2+ and phospholipids: responsiveness to these effectors however is conferred by previous fragmentation of protamine with thermolysin. These results suggest that Ca2+, phospholipid-independent phosphorylation of protamine by protein kinase C might have physiological relevance and shed light on the structural basis for the specificity of such an unique process.
