Supt4a - SPT4A, DSIF elongation factor subunit

Predicted to enable RNA polymerase II complex binding activity and protein heterodimerization activity. Acts upstream of or within negative regulation of transcription elongation from RNA polymerase II promoter. Predicted to be located in nucleoplasm. Predicted to be part of DSIF complex. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Orthologous to human SUPT4H1 (SPT4 homolog, DSIF elongation factor subunit).
