NOMENCLATURE CONFLICT NOTE

NameRelevanceDescription
GNA1Nomenclature conflictPAT1 has been used in the literature to refer to both PAT1/YCR077C, which is involved in translational initiation and chromosome segregation and GNA1/YFL017C, which encodes a glucosamine-phosphate N-acetyltransferase.
PXA2Nomenclature conflictPAT1 has been used in the literature to refer to both PAT1/YCR077C, which is involved in translational initiation and chromosome segregation, and PXA2/YKL188C, which encodes a ABC transporter-2.
