Human Myristoylated Alanine-Rich C-Kinase Substrate (MARCKS) ELISA Kit | MARCKS elisa kit
Human Myristoylated Alanine-Rich C-Kinase Substrate (MARCKS) ELISA Kit
* Allow all reagents to warm to room temperature for at least 30 minutes before opening.
* Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
* Unused wells must be kept desiccated at 4 degree C in the sealed bag provided.
* Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
* It is recommended that all samples and standards be assayed in duplicate or triplicate.
Background: MARCKS is a substrate for protein kinase C. It is localized to the plasma membrane and is an actin filament crosslinking protein. Phosphorylation by protein kinase C or binding to calcium-calmodulin inhibits its association with actin and with the plasma membrane, leading to its presence in the cytoplasm. MARCKS is a filamentous actin crosslinking protein, with activity that is inhibited by PKC-mediated phosphorylation and by binding to calcium-calmodulin. MARCKS may be a regulated crossbridge between actin and the plasma membrane, and modulation of the actin crosslinking activity of the MARCKS protein by calmodulin and phosphorylation represents a potential convergence of the calcium-calmodulin and protein kinase C signal transduction pathways in the regulation of the actin cytoskeleton.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a substrate for protein kinase C. It is localized to the plasma membrane and is an actin filament crosslinking protein. Phosphorylation by protein kinase C or binding to calcium-calmodulin inhibits its association with actin and with the plasma membrane, leading to its presence in the cytoplasm. The protein is thought to be involved in cell motility, phagocytosis, membrane trafficking and mitogenesis. [provided by RefSeq, Jul 2008]
Uniprot Description
MARCKS: the most prominent cellular substrate of protein kinase C. Binds calmodulin, actin, and synapsin. A filamentous actin cross-linking protein. Critical for normal brain development. Phosphorylation by PKC displaces it from the plasma membrane, inhibiting F-actin cross-linking activity. Plays a role in growth cone adhesion: its nonphosphorylated form stabilizes integrin-mediated adhesions, and its phosphorylation-triggered release from adhesions causes localized growth cone detachment. Highly expressed in immature T and B lymphocytes: its expression is highest in CD4-8- T cells and B-cell blasts generated by antigen receptor signaling. Its expression and phosphorylation are closely linked to microglial activation processes involved in pathological conditions such as neuroinflammation and neurodegeneration.

Product Notes
The Human MARCKS marcks (Catalog #AAA9715386) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9715386 ELISA Kit recognizes Human MARCKS. It is sometimes possible for the material contained within the vial of "Myristoylated Alanine-Rich C-Kinase Substrate (MARCKS), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
