ID:NELFB_HUMAN DESCRIPTION: RecName: Full=Negative elongation factor B; Short=NELF-B; AltName: Full=Cofactor of BRCA1; FUNCTION: 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. May be able to induce chromatin unfolding. SUBUNIT: The NELF complex is composed of 4 subunits: WHSC2/NELF-A, COBRA1/NELF-B, TH1L (isoform NELF-C or isoform NELF-D) and RDBP/NELF-E. Interacts with the first BRCT repeat of BRCA1. Interacts with KIAA1191. INTERACTION: P38398:BRCA1; NbExp=5; IntAct=EBI-347721, EBI-349905; O43583:DENR; NbExp=2; IntAct=EBI-347721, EBI-716083; P06241:FYN; NbExp=2; IntAct=EBI-347721, EBI-515315; P62993:GRB2; NbExp=2; IntAct=EBI-347721, EBI-401755; P38646:HSPA9; NbExp=2; IntAct=EBI-347721, EBI-354932; O75525:KHDRBS3; NbExp=2; IntAct=EBI-347721, EBI-722504; P10620:MGST1; NbExp=2; IntAct=EBI-347721, EBI-2691601; P16333:NCK1; NbExp=6; IntAct=EBI-347721, EBI-389883; P27986:PIK3R1; NbExp=2; IntAct=EBI-347721, EBI-79464; P18615:RDBP; NbExp=3; IntAct=EBI-347721, EBI-348444; SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Widely expressed. Expressed in heart, brain, lung, placenta, liver, skeletal muscle, kidney and pancreas. SIMILARITY: Belongs to the NELF-B family. SEQUENCE CAUTION: Sequence=AAH11892.1; Type=Erroneous initiation; Sequence=BAB14157.1; Type=Erroneous initiation; Sequence=CAB43381.3; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
