Applications

Our Abpromise guarantee covers the use of ab55975 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
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay: 1:312500.

WB Use a concentration of 2.5 µg/ml. Detects a band of approximately 75 kDa (predicted molecular weight: 106 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.

Target

  • FunctionMay be a transcription regulator involved in cell-cycle progression and skeletal muscle differentiation. May repress GTF2I transcriptional functions, by preventing its nuclear residency, or by inhibiting its transcriptional activation. May contribute to slow-twitch fiber type specificity during myogenesis and in regenerating muscles. Binds troponin I slow-muscle fiber enhancer (USE B1). Binds specifically and with high affinity to the EFG sequences derived from the early enhancer of HOXC8.
  • Tissue specificityHighly expressed in adult skeletal muscle, heart, fibroblast, bone and fetal tissues. Expressed at lower levels in all other tissues tested.
  • Involvement in diseaseNote=GTF2IRD1 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region. Haploinsufficiency of GTF2IRD1 may be the cause of certain cardiovascular and musculo-skeletal abnormalities observed in the disease.
  • Sequence similaritiesBelongs to the TFII-I family.
    Contains 5 GTF2I-like repeats.
  • Developmental stageHighly expressed in developing and regenerating muscles, at the time of myofiber diversification.
  • DomainThe N-terminal half may have an activating activity.
  • Cellular localizationNucleus.
