Acidic calmodulin binding protein, ACAMP-81, is MARCKS protein interacting with synapsin I.
ACAMP-81 is an acidic calmodulin binding protein with molecular mass of 81 kDa. We report partial amino acid analysis of ACAMP-81 and its interaction with synapsin I. 123 amino acids of ACAMP-81 were determined and the sequence was completely identical with that of MARCKS protein which was thought to be a substrate for calcium/phospholipid dependent protein kinase (PKC). We found ACAMP-81 bound to synapsin I with 125I-labeled ACAMP-81 overlay method. ACAMP-81 bound to the cysteine specific cleaved 51 kDa fragment derived from middle/tail region of synapsin I.
