Genes affected

TCEA1 (HGNC:11612): (transcription elongation factor A1) Predicted to enable DNA binding activity; translation elongation factor activity; and zinc ion binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within erythrocyte differentiation and positive regulation of transcription, DNA-templated. Located in nucleolus and nucleoplasm. Part of transcription factor TFIID complex. [provided by Alliance of Genome Resources, Apr 2022]
