描述 Anti-Caldesmon Antibody, clone TD107 背景信息 Caldesmon is a protein component of the thin filaments of smooth muscle myofibrils. It
is also localized in the stress fibers of fibroblasts. Caldesmon was identified as a
Ca2+/Calmodulin-binding protein with molecular weight of 120-150kDa (H-Caldesmon)
and 70-80kDa (L-Caldesmon). H-Caldesmon is the primary isoform in smooth muscle
while L-Caldesmon is most abundant in non-muscle cells. Caldesmon is capable of
binding two calmodulin molecules, one at either end of the protein. Additionally,
Caldesmon is an actin, myosin, and tropomyosin-binding protein. Human L-Caldesmon
is a protein of 538 amino acids with mobility of 80kDa. In vitro, L-Caldesmon inhibits
the actomyosin ATPase in an F-Actin-dependent manner. L-Caldesmon may play an
important function in motile processes such as secretion and organelle movement.产品信息 格式 Ascites 演示 Ascites fluid. Liquid 应用 应用 Anti-Caldesmon Antibody, clone TD107 is an antibody against Caldesmon for use in IF, IP, WB, IC, IH. 主要应用 - Immunohistochemistry

应用说明 Immunoblotting 1:50-1:100
Immunoprecipitation
Immunofluorescence
3.7% formaldehyde fixation 10' 4C; permeabilization 0.2% triton X-100 in PBST for 5 minutes, blocked with 2% BSA in PBST for 20 minutes. Primary antibody 1:100 for 1 hour at room temperature {Garcia et al 2002}.

Immunohistochemistry
Optimal working dilutions must be determined by end user.生物信息 免疫原品种 Human platelet protein. 克隆 TD107 宿主 Mouse 特异性 Human caldesmon. Reacts with the caldesmon protein (80kD) (LMW form) from platelets by Western blotting.Crossreacts with the 140kD (HMW) isoform of smooth muscle.
The HMW (120-150kDa) is predominantly expressed in smooth muscle whereas LMW caldesmon (70-80kDa) is found in nonmuscle tissue and cells. Neither of the two isoforms has been detected in skeletal muscle.同种型 IgG1 品种反应性 Yeast (S. cerevisiae)AvianHumanMammals 抗体类型 Monoclonal Antibody Entrez基因编号 - NM_033157.2

Entrez基因汇总 This gene encodes a calmodulin- and actin-binding protein that plays an essential role in the regulation of smooth muscle and nonmuscle contraction. The conserved domain of this protein possesses the binding activities to Ca(2+)-calmodulin, actin, tropomyosin, myosin, and phospholipids. This protein is a potent inhibitor of the actin-tropomyosin activated myosin MgATPase, and serves as a mediating factor for Ca(2+)-dependent inhibition of smooth muscle contraction. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. 基因符号 - H-CAD

UniProt编号 - Q05682
UniProt汇总 FUNCTION: SwissProt: Q05682 # Actin- and myosin-binding protein implicated in the regulation of actomyosin interactions in smooth muscle and nonmuscle cells (could act as a bridge between myosin and actin filaments). Stimulates actin binding of tropomyosin which increases the stabilization of actin filament structure. In muscle tissues, inhibits the actomyosin ATPase by binding to F-actin. This inhibition is attenuated by calcium-calmodulin and is potentiated by tropomyosin. Interacts with actin, myosin, two molecules of tropomyosin and with calmodulin. Also play an essential role during cellular mitosis and receptor capping.
SIZE: 793 amino acids; 93250 Da
SUBCELLULAR LOCATION: Note=On thin filaments in smooth muscle and on stress fibers in fibroblasts (nonmuscle) (By similarity).
TISSUE SPECIFICITY: High-molecular-weight caldesmon (isoform 1) is predominantly expressed in smooth muscles, whereas low-molecular- weight caldesmon (isoforms 2, 3, 4 and 5) are widely distributed in non-muscle tissues and cells. Not expressed in skeletal muscle or heart.
DOMAIN: SwissProt: Q05682 The N-terminal part seems to be a myosin/calmodulin- binding domain, and the C-terminal a tropomyosin/actin/calmodulin- binding domain. These two domains are separated by a central helical region in the smooth-muscle form.
PTM: In non-muscle cells, phosphorylation by CDC2 during mitosis causes caldesmon to dissociate from microfilaments. Phosphorylation reduces caldesmon binding to actin, myosin, and calmodulin as well as its inhibition of actomyosin ATPase activity. Phosphorylation also occurs in both quiescent and dividing smooth muscle cells with similar effects on the interaction with actin and calmodulin and on microfilaments reorganization (By similarity).
SIMILARITY: Belongs to the caldesmon family.产品使用声明 使用声明 - Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
