About GTF2A1

Cytogenetic location: 14q31.1 Genomic coordinates (GRCh38): 14:81,175,452-81,221,390 (from NCBI)

This gene has 4 transcripts (splice variants), 213 orthologues and 1 paralogue. Ubiquitous expression in thyroid (RPKM 15.3), testis (RPKM 12.9) and 25 other tissues.

Summary

Accurate transcription initiation on TATA-containing class II genes involves the ordered assembly of RNA polymerase II (POLR2A; MIM 180660) and several general initiation factors (summarized by DeJong and Roeder, 1993 [PubMed 8224848]). One of these factors is TFIIA, which when purified from HeLa extracts consists of 35-, 19-, and 12-kD subunits.[supplied by OMIM, Jul 2010]
