GABPA
(redirected from GA-binding protein transcription factor, alpha subunit)GABPA
A gene on chromosome 21q21.3 that encodes the alpha subunit of the GA-binding protein, which forms a tetrameric complex with two beta subunits and stimulates transcription of target genes. The encoded protein may downregulate cytochrome oxidase expression and may play a role in nuclear control of mitochondrial function.Segen's Medical Dictionary. © 2012 Farlex, Inc. All rights reserved.
