MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Mice homozygous for a hypomorphic allele where D/G cleavage residues are replaced with noncleavable A/A show neonatal lethality, feeding defects, low testis weight, and male infertility associated with azoospermia, small seminiferous tubules, lack of elongating spermatids, and increased apoptosis.
