SKU:: 052091
Application:: WB
Purity:: Purified by immunoaffinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Rabbit
Immunogen:: Synthetic peptide corresponding to amino acid residues at the C-terminus from mouse MYH4/MyHC-IIB, conjugated to KLH. This sequence has 100% identity with rat and human MYH4, and has significant homology to MYH1, MYH2, and MYH8.
Format:: Supplied as a liquid in PBS, 1mg/ml BSA, 0.05% sodium azide, 50% glycerol.
Extra Details:: Non-muscle myosin II is an actin-based motor protein essential to cell motility, cell division, migration, adhesion and polarity. This myosin forms a hexameric complex comprised of two heavy chains (NMHC-II), two essential light chains, and two regulatory light chains (RLC). In vertebrates, there are three NMHC-II isoforms (NMHC-IIA, NMHC-IIB, and NMHC-IIC), which exhibit distinct patterns of expression in cells and tissues. Regulation of NMHC-II activity occurs through RLC and HC phosphorylation. RLCs are phosphorylated at Thr-18 and Ser-19, leading to activation of myosin II motor activity and increased myosin filament stability. By contrast, PKC phosphorylation of Ser-1/Ser-2 and Thr-9 in RLC may decrease activated myosin II interaction with actin. NMHC-II phosphorylation may be an important mode for regulating myosin-II assembly. PKC phosphorylates NMHC-IIA on Ser-1916 in the C-terminal region and NMHC-IIB on multiple serines in the tailpiece. Casein kinase II phosphorylates NMHC-IIA on Ser-1943 in the tailpiece and increases disassembly of NMHC-IIA filaments. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:2000, detects a 215kD protein corresponding to the apparent molecular mass of MYH4 on SDS-PAGE immunoblots of mouse extraocular muscle and mouse C2C12 cells. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
