GTF2B - general transcription factor IIB Gene

Homo sapiens

Also known as TF2B; TFIIB

Gene ID: 2959 | Gene type: protein coding

About GTF2B

Cytogenetic location: 1p22.2 Genomic coordinates (GRCh38): 1:88,852,633-88,891,567 (from NCBI)

This gene has 7 transcripts (splice variants), 223 orthologues and 2 paralogues. Ubiquitous expression in bone marrow (RPKM 18.5), gall bladder (RPKM 11.2) and 25 other tissues.

Summary

This gene encodes the general transcription factor IIB, one of the ubiquitous factors required for transcription initiation by RNA polymerase II. The protein localizes to the nucleus where it forms a complex (the DAB complex) with transcription factors IID and IIA. Transcription factor IIB serves as a bridge between IID, the factor which initially recognizes the promoter sequence, and RNA polymerase II. [provided by RefSeq, Jul 2008]
