Sea urchin sperm head plasma membranes: characteristics and egg jelly induced Ca2+ and Na+ uptake.

García-Soto J, Mourelle M, Vargas I, de De la Torre L, Ramírez E, López-Colomé AM, Darszon A. García-Soto J, et al. Among authors: darszon a. Biochim Biophys Acta. 1988 Sep 15;944(1):1-12. doi: 10.1016/0005-2736(88)90310-0. Biochim Biophys Acta. 1988. PMID: 2458136

Phosphatidylcholine was higher in the head membranes, while phosphatidylserine and phosphatidylethanolamine were lower. The head membranes displayed a 1.7-2.3-fold higher Ca2+-ATPase activity and a 2.5-fold lower Na+/K+-ATPase activity, than the flagellar membranes. …
