Applications

Reactivity

Human
Mouse
Rat

Overview
Catalog #	bs-70549r-100ul
Product Name	Myosin IIA Heavy Chain (C-terminal region) Antibody
Applications	WB
Specificity	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. 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.
Reactivity	Human, Mouse, Rat
Specifications
Conjugation	Unconjugated
Host	Rabbit
Source	NMHC-IIA synthetic peptide (coupled to KLH) corresponding to amino acid residues in the C-terminal region of human myosin IIA heavy chain.
Clonality	Polyclonal
Isotype	IgG
Purification	Antigen Affinity purification
Storage Buffer	PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
Storage Condition	Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Target
Swiss Prot	P35579
Synonyms	NMHC-IIA, MYH9, myosin heavy chain
Background	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.
