Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Phospho-MARCKS (Ser152/156) Antibody detects endogenous levels of MARCKS only when phosphorylated at serines 152 and 156 .

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic phospho-peptide (KLH coupled) corresponding to residues surrounding Ser152/156 of rat MARCKS. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from NIH/3T3 and C6 cells starved for 16 hours and treated with TPA (0.2 µM) for 30 minutes.

Background

Myristoylated alanine-rich protein kinase C substrate (MARCKS) is a major PKC substrate that is distributed in various cell types. MARCKS has been implicated in cell motility, cell adhesion, phagocytosis, membrane traffic and mitogenesis (1). PKC phosphorylates Ser152, 156 and 163 of MARCKS (2), which regulates MARCKS's calcium/calmodulin binding activity and filamentous (F)-actin cross-linking activity (3,4). In addition, phosphorylation by PKC results in translocation of MARCKS from membrane to cytoplasm (5).
