AIR1 [YIL079C]
Arginine methyltransferase-interacting RING finger protein 1; 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
Synonyms: AIR1, AIR1p, P40507, P40507p, YIL079C ...
