SIT1 and breast cancer: Interestingly, 3 genes (Clusters 67, 100, 40) identified in the JAY291 and GLBRCY22-3 bioethanol strains, a low-affinity NH4+ transporter (AMF71), a Zinc finger transcription factor (ZTF2) and a siderophore iron transporter with similarity to S288c SIT1 and ARN1 were identified in the TPO clade strain OK047 and 29% (10/34) of the BC strains in the PWCW clade but only in 1 WE clade strain (SBV171) and in neither of the BC strains in the Beer 1/Mixed Origin clade (Fig. 7a) (Argueso et al. 2009; McIlwain et al. 2016).
