Genes affected

MESP1 (HGNC:29658): (mesoderm posterior bHLH transcription factor 1) Enables DNA-binding transcription factor activity and transcription cis-regulatory region binding activity. Involved in several processes, including endothelial cell differentiation; heart development; and positive regulation of transcription by RNA polymerase II. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
