Our Abpromise guarantee covers the use of ab49311 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 10 µg/ml.
IP Use at an assay dependent concentration. PubMed: 23243284
WB Use a concentration of 1.25 µg/ml. Detects a band of approximately 109 kDa (predicted molecular weight: 99 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay: 1:1562500.


  • FunctionTranscriptional coactivator of serum response factor (SRF) with the potential to modulate SRF target genes. Suppresses TNF-induced cell death by inhibiting activation of caspases; its transcriptional activity is indispensable for the antiapoptotic function. It may up-regulate antiapoptotic molecules, which in turn inhibit caspase activation.
  • Tissue specificityUbiquitously expressed, has been detected in lung, placenta, small intestine, liver, kidney, spleen, thymus, colon, muscle, heart and brain.
  • Involvement in diseaseNote=A chromosomal aberration involving MKL1 may be a cause of acute megakaryoblastic leukemia. Translocation t(1;22)(p13;q13) with RBM15. Although both reciprocal fusion transcripts are detected in acute megakaryoblastic leukemia (AMKL, FAB-M7), the RBM15-MKL1 chimeric protein has all the putative functional domains encoded by each gene and is the candidate oncogene.
  • Sequence similaritiesContains 2 RPEL repeats.
    Contains 1 SAP domain.
  • DomainThe N-terminal region is required for nuclear localization and the C-terminal region mediates transcriptional activity.
    The RPEL repeats mediate binding to globular actin.
  • Cellular localizationCytoplasm. Nucleus. Binding to globular actin is required to maintain cytoplasmic localization.

  • ICC/IF image of ab49311 stained MEF1 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab49311, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
