RUNX1

A gene on chromosome 21q22.3 that encodes the alpha subunit of core binding factor (CBF), a heterodimeric transcription factor that binds to the core element of many enhancers and promoters. RUNX1 is thought to be involved in the development of normal haematopoiesis. 

Molecular pathology
Chromosomal translocations involving RUNX1 are well documented and associated with several types of leukaemia.

NSA has provided a summary of the changes: You must swap from the old AML1 form to the new ARAMS form and send it to SouthWestern instead of your local authority.
After sonication, 5 [micro]g of antibodies recognizing the following AML1 (Santa Cruz Biotechnology, Santa Cruz, USA, sc-28679), ETO (Santa Cruz Biotechnology, Santa Cruz, USA, sc-9737), histone deacetylase 1 (HDAC1) (Abcam, Cambridge, USA, ab7028), DNA methyltransferase 1 (DNMT1) (Abcam, Cambridge, USA, ab13537), DNMT3a (Abcam, Cambridge, USA, ab13888) and DNMT3b (Abcam, Cambridge, USA, ab13604) were immunoprecipitated with the chromatin overnight.
We then observed that the expression of AML1-ETO could cause a dose-dependent decrease in the luciferase reporter activity of the EYA4-P1, but not in its mutant EYA4-M and EYA4-P2 that lack any functional AML1 binding site [Figure 2]b.
Therefore, the chromatin remodeling complex which was aberrantly formed by AML1-ETO, and the hypermethylation of the CpG islands which were presented in the AML1 binding sites on the EYA4 regulatory region appeared to be the key regulatory mechanisms for the transcriptional silencing of EYA4 .
This will be very similar to the current AML1 document with a few minor changes.
