Gene: GABPB1 (GA binding protein transcription factor subunit beta 1) Homo sapiens
Symbol: GABPB1
Name: GA binding protein transcription factor subunit beta 1
Description: Exhibits protein heterodimerization activity and transcription regulatory region DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Localizes to the cytoplasmic ribonucleoprotein granule and nucleoplasm.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: BABPB2; E4TF1; E4TF1-47; E4TF1-53; E4TF1B; GA binding protein transcription factor beta subunit 1; GA binding protein transcription factor beta subunit 1 transcript variant gamma-2; GA binding protein transcription factor, beta subunit 1; GA-binding protein subunit beta-1; GABP subunit beta-1; GABP subunit beta-2; GABPB; GABPB-1; GABPB-2; GABPB2; NRF2B1; NRF2B2; nuclear respiratory factor 2; transcription factor E4TF1-47; transcription factor E4TF1-53
Allele / Splice: See ClinVar data
Latest Assembly: GRCh38 - Human Genome Assembly GRCh38
NCBI Annotation Information: Note: In August, 2008, the nomenclature of the GA binding protein transcription factors was clarified. The gene on Hsa1q was named GABPB2 and the gene on Hsa15q was named GABPB1. [24 Sep 2008]
