Target

  • Function

    Transcription factor that is involved in embryonic development, establishment of tissue-specific gene expression and regulation of gene expression in differentiated tissues. Is thought to act as a 'pioneer' factor opening the compacted chromatin for other proteins through interactions with nucleosomal core histones and thereby replacing linker histones at target enhancer and/or promoter sites. Binds DNA with the consensus sequence 5'-[AC]A[AT]T[AG]TT[GT][AG][CT]T[CT]-3' (By similarity). Proposed to play a role in translating the epigenetic signatures into cell type-specific enhancer-driven transcriptional programs. Its differential recruitment to chromatin is dependent on distribution of histone H3 methylated at 'Lys-5' (H3K4me2) in estrogen-regulated genes. Involved in the development of multiple endoderm-derived organ systems such as liver, pancreas, lung and prostate; FOXA1 and FOXA2 seem to have at least in part redundant roles (By similarity). Modulates the transcriptional activity of nuclear hormone receptors. Is involved in ESR1-mediated transcription; required for ESR1 binding to the NKX2-1 promoter in breast cancer cells; binds to the RPRM promter and is required for the estrogen-induced repression of RPRM. Involved in regulation of apoptosis by inhibiting the expression of BCL2. Involved in cell cycle regulation by activating expression of CDKN1B, alone or in conjunction with BRCA1. Originally discribed as a transcription activator for a number of liver genes such as AFP, albumin, tyrosine aminotransferase, PEPCK, etc. Interacts with the cis-acting regulatory regions of these genes. Involved in glucose homeostasis.
  • Tissue specificity

    Highly expressed in prostate and ESR1-positive breast tumors. Overexpressed in esophageal and lung adenocarcinomas.
  • Sequence similarities

    Contains 1 fork-head DNA-binding domain.
  • Cellular localization

    Nucleus.

    Is this antibody specific to FoxA1 or does it recognize the related family member FoxA2 (that contains part of the immunogen sequence) ? Thanks

    Asked on Aug 10 2006

    Answer

    Thank you for your enquiry regarding the specificity of our antibody raised against FOXA1 (ab5089). There is 72% sequence homology between the FOXA1 synthetic peptide immunogen used to raise this antibody and FOXA2. This means there is a small chance that it will also detect FOXA2, perhaps giving some weak staining from cross-reactivity. I am sorry that to my knowledge there is no experimental data available on this. I hope this helps. Please get back to me if you have any more questions and I will be happy to help.

    Asked on Nov 15 2005

    Answer

    Thank you for your enquiry and patience. I enquired with the originator of this antibody and we cannot find references to FOXA1 isoforms in Entrez Gene or SwissProt. The sequence of the immunogen used to generate this antibody is as follows: GVYSRPVLNTS, corresponding to amino acids 463-473 of Human FOX A1. So if you have the sequences of the isoforms, you can compare the immunogen sequence with them. Please contact us again if you have any additional questions.
