Zinc knuckle protein; involved in nuclear RNA processing and degradation as a component of the TRAMP complex; stimulates the poly(A) polymerase activity of Pap2p in vitro; AIR1 has a paralog, AIR2, that arose from the whole genome duplication; although Air1p and Air2p are homologous TRAMP subunits, they have nonredundant roles in regulation of substrate specificity of the exosome [Source:SGD;Acc:S000001341]
Chromosome IX: 210,923-212,005 reverse strand.
R64-1-1:BK006942.2
This gene has 1 transcript (splice variant), 48 orthologues and 1 paralogue.
