1 MARCKS protein is phosphorylated and regulates calcium mobilization during human acrosomal exocytosis. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
2 Calcium- and phorbol ester-triggered acrosomal exocytosis in permeabilized sperm was abrogated by different anti-MARCKS antibodies raised against two different domains, indicating that the protein participates in acrosomal exocytosis. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
3 We found that PIP2 and adenophostin, a potent IP3-receptor agonist, rescued MARCKS inhibition in permeabilized sperm, suggesting that MARCKS inhibits acrosomal exocytosis by sequestering PIP2 and, indirectly, MARCKS regulates the intracellular calcium mobilization. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
4 We found that PIP2 and adenophostin, a potent IP3-receptor agonist, rescued MARCKS inhibition in permeabilized sperm, suggesting that MARCKS inhibits acrosomal exocytosis by sequestering PIP2 and, indirectly, MARCKS regulates the intracellular calcium mobilization. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
5 In non-permeabilized sperm, a permeable peptide of MARCKS ED also inhibited acrosomal exocytosis when stimulated by a natural agonist such as progesterone, and pharmacological inducers such as calcium ionophore and phorbol ester. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
6 The preincubation of human sperm with the permeable MARCKS ED abolished the increase in calcium levels caused by progesterone, demonstrating that MARCKS regulates calcium mobilization. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
7 The preincubation of human sperm with the permeable MARCKS ED abolished the increase in calcium levels caused by progesterone, demonstrating that MARCKS regulates calcium mobilization. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
8 The preincubation of human sperm with the permeable MARCKS ED abolished the increase in calcium levels caused by progesterone, demonstrating that MARCKS regulates calcium mobilization. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
9 The preincubation of human sperm with the permeable MARCKS ED abolished the increase in calcium levels caused by progesterone, demonstrating that MARCKS regulates calcium mobilization. Calcium myristoylated alanine rich protein kinase C substrate Homo sapiens
