The monoclonal antibody ALB6 directed against the leukocyte differentiation antigen CD9 (p24) increases the calcium incorporation into isolated platelet membrane vesicles enriched in internal membranes. The similarities of the effects of both the monoclonal antibody and the catalytic subunit of the cAMP-dependent protein kinase (C, subunit), which phosphorylates a protein of an apparent molecular mass of 23 kDa, led us to investigate the relationship between CD9 (p24) and the 23-kDa phosphoprotein (p23). ALB6IgG does not inhibit the C.subunit-induced phosphorylation of p23 and the immunoadsorption by ALB6IgG of p24 associated to membrane vesicles does not alter the phosphorylation pattern. Thus, proteins of similar molecular mass appear to be involved in calcium fluxes: one is recognized by the ALB6 antibody while the other can be phosphorylated by the C-subunit.
