機能Essential component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II. The NELF complex, which acts via an association with the DSIF complex and causes transcriptional pausing, is counteracted by the P-TEFb kinase complex. Probably required to interact with the RNA polymerase II complex.
組織特異性Ubiquitous. Expressed in heart, brain, placenta, liver, skeletal muscle, kidney and pancreas. Expressed at lower level in adult lung. Expressed in fetal brain, lung, liver and kidney.
配列類似性Belongs to the NELF-A family. Contains 1 HDAg-like domain.
ドメインThe HDAg-like domain is essential for transcriptional repression, and mediates the interaction with the RNA polymerase II complex.
