Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Species predicted to react based on 100% sequence homology: Chicken, Bovine.
Specificity / Sensitivity
Phospho-MARCKS (Ser167/170) (D13E4) XP® Rabbit mAb recognizes endogenous levels of MARCKS protein only when phosphorylated at Ser167 and Ser170. This antibody may also detect MARCKS mono-phosphorylated at Ser167.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser167 and Ser170 of human MARCKS protein.
Western blot analysis of extracts from serum-starved SH-SY5Y and SK-N-MC cells, untreated (-) or treated with TPA #4174 (200 nM, 15 min; +), using Phospho-MARCKS (Ser167/170) (D13E4) XP® Rabbit mAb (upper) and MARCKS (D88D11) XP® Rabbit mAb #5607 (lower).
Western blot analysis of extracts from various cell lines, serum-starved overnight and then untreated (-) or treated with TPA #4174 (200 nM, 15 min; +), using Phospho-MARCKS (Ser167/Ser170) (D13E4) XP® Rabbit mAb.
Flow cytometric analysis of HeLa cells, serum starved (blue) or serum starved and treated with TPA #4174 (200nM, 15 min; green), using Phospho-MARCKS (Ser167/170) (D13E4) XP® Rabbit mAb. Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 647 Conjugate) #4414 was used as a secondary Ab.
Myristoylated Alanine-Rich C-Kinase Substrate (MARCKS) is a major PKC substrate expressed in many cell types. MARCKS has been implicated in cell motility, cell adhesion, phagocytosis, membrane traffic, and mitogenesis (1). PKC phosphorylates Ser159, 163, 167, and 170 of MARCKS in response to growth factors and oxidative stress. Phosphorylation at these sites regulates the calcium/calmodulin binding and filamentous (F)-actin cross-linking activities of MARCKS (2-4). Phosphorylation by PKC also results in translocation of MARCKS from the plasma membrane to the cytoplasm (5).
