Anti-Myosin IIA Heavy Chain (C-terminal region) Antibody

Nonmuscle 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.

Our Myosin IIA Heavy Chain (C-terminal region) rabbit polyclonal primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat Myosin IIA Heavy Chain (C-terminal region) and is antigen affinity purified. It is great for use in WB, ICC.

NMHC-IIA synthetic peptide (coupled to KLH) corresponding to amino acid residues in the C-terminal region of human myosin IIA heavy chain. This peptide sequence is highly conserved in rat and mouse NMHC-IIA, but is not found in NMHC-IIB and is not well conserved in NMHC-IIC.

The antibody detects a 200 kDa* protein corresponding to the apparent molecular mass of NMHC-IIA on SDS-PAGE immunoblots of human A431, Jurkat, mouse C2C12, and rat PC12 cells.
