Description
Constitutive targeting of Tem1 to the spindle pole body (SPB) in metaphase cells (this image) and anaphase cells (CIL#13887). tem1Δ::GAL-UPL-TEM1 cells expressing eGFP-BFA1–TEM1 from a CEN plasmid were grown on 2% raffinose/2% galactose. Image shows localization of Bfa1-Tem1 (eGFP, green) in metaphase after cells were transferred to medium with 2% glucose. Tem1 normally localizes preferentially to the SPB that enters the daughter cell during anaphase (CIL# 13882, 13885). Localization of Bfa1 is similar to that of Tem1, but Bfa1 is more stable on the SPB in the daughter cell and more asymmetric than Tem1 in late anaphase. The Bfa1-Tem1 fusion protein localization resembles Bfa1. Nuclear morphology was assessed by DAPI (blue). A differential interference contrast (DIC) image is also shown (gray). The tem1Δ::GAL1-UPL-TEM1 strain allows for the rapid, conditional depletion of Tem1. UPL, which stands for ubiquitin-proline-LacI, acts as a destabilizing module that permits rapid degradation of appended proteins. Image is Fig 1A, bottom panels, in J Cell Biol. (2011) 192: 599-614.
