Target

  • Function
    Muscle contraction.
  • Tissue specificity
    Smooth muscle; expressed in the umbilical artery, bladder, esophagus and trachea.
  • Involvement in disease
    Note=A chromosomal aberration involving MYH11 is found in acute myeloid leukemia of M4EO subtype. Pericentric inversion inv(16)(p13;q22). The inversion produces a fusion protein consisting of the 165 N-terminal residues of CBF-beta (PEPB2) and the tail region of MYH11.
    Defects in MYH11 are the cause of aortic aneurysm familial thoracic type 4 (AAT4) [MIM:132900]; also known as familial thoracic aortic aneurysm and dissection (TAAD). Aneurysms and dissections of the aorta usually result from degenerative changes in the aortic wall. Thoracic aortic aneurysms and dissections are primarily associated with a characteristic histologic appearance known as 'medial necrosis' or 'Erdheim cystic medial necrosis' in which there is degeneration and fragmentation of elastic fibers, loss of smooth muscle cells, and an accumulation of basophilic ground substance. Patients with AAT4 show marked aortic stiffness. Pathological aortas show large areas of medial degeneration with very low smooth muscle cells content.
  • Sequence similarities
    Contains 1 IQ domain.
    Contains 1 myosin head-like domain.
  • Domain
    The rodlike tail sequence is highly repetitive, showing cycles of a 28-residue repeat pattern composed of 4 heptapeptides, characteristic for alpha-helical coiled coils.
    Each myosin heavy chain can be split into 1 light meromyosin (LMM) and 1 heavy meromyosin (HMM). It can later be split further into 2 globular subfragments (S1) and 1 rod-shaped subfragment (S2).
  • Cellular localization
    Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Thick filaments of the myofibrils.

  • ab683 staining smooth muscle Myosin heavy chain 11 in rat cells from cells from mesenteric artery by ICC/IF. Cells were PFA fixed and permeabilized in 0.3% Triton X-100 prior to blocking in 2% serum for 30 minutes at 20°C. The primary antibody was diluted 1/300 and incubated with the sample for 14 hours at 4°C. Alexa Fluor® 488 chicken polyclonal to mouse Ig, diluted 1/400, was used as the secondary. Nuclei stained with Hoechst 33342.

  • ab683 staining smooth muscle Myosin heavy chain 11 in human cerebral artery tissue sections by Immunohistochemistry (IHC-P - Formalin/PFA-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde, permeabilized with 0.3% Triton-X and blocked with 5% serum for 1 hour at 25°C; antigen retrieval was by heat mediation in sodium citrate. Samples were incubated with the primary antibody (1/500) for 16 hours at 4°C. A biotin-conjugated rabbit anti-mouse IgG polyclonal (1/300) was used as the secondary antibody.

Cells were fixed with paraformaldehyde, permeabilized with 0.3% Triton X-100 and blocked with 2% BSA for 30 minutes at 20°C. Samples were incubated with the primary antibody (1/300 in PBS) for 14 hours at 4°C. An Alexa Fluor® 488-conjugated chicken anti-mouse IgG polyclonal (1/400) was used as the secondary antibody.

Answer

I have just received the following information regarding the immunogen sequences of our myosin heavy chain antibodies: AA sequences of the antigens (C-terminus) are as follows: ab682 : GPPPQETSQ ab683: DADFNGTKSSE ab684 : TSDVNETQPPQSE Therefore the homology percentages with these immunogens and the chicken protein are: ab682: 87% (7/8 aa are identical) ab683: 72% (8/11aa are identical) ab684: 66% (8/12aa are identical) I hope this information will help you decide whether to try those antibodies in chicken, Please let me know if I can be of further assistance,
