Gene Type: protein coding
Gene ID: 25920

About NELFB

Cytogenetic location: 9q34.3 Genomic coordinates (GRCh38): 9:137,255,327-137,273,542 (from NCBI)

This gene has 1 transcript (splice variant) and 203 orthologues. Ubiquitous expression in testis (RPKM 16.5), fat (RPKM 16.5) and 25 other tissues.

Summary

NELFB is a subunit of negative elongation factor (NELF), which also includes NELFA (WHSC2; MIM 606026), either NELFC or NELFD (TH1L; MIM 605297), and NELFE (RDBP; MIM 154040). NELF acts with DRB sensitivity-inducing factor (DSIF), a heterodimer of SPT4 (SUPT4H1; MIM 603555) and SPT5 (SUPT5H; MIM 602102), to cause transcriptional pausing of RNA polymerase II (see MIM 180660) (Narita et al., 2003 [PubMed 12612062]).[supplied by OMIM, Mar 2008]
