FIGURE 4:
Chs6(ΔTPR1-4) fails to interact with other exomer components. (A) Chs6(ΔTPR1-4) failed to bind to Chs5p, whereas Chs6(ΔTPR5) still interacted. Coimmunoprecipitation experiments were performed using an anti-Chs5p antibody and lysates generated from cells expressing chromosomally tagged Chs6(ΔTPR1-4)-9myc or Chs6(ΔTPR5)-9myc. (B) Chs6(ΔTPR1-4) also failed to coprecipitate with other ChAPs, such as Bch1p. Blue, Chs6p alleles; red, Bch1p alleles. Two different exposures were cropped together because of the strong signal of the precipitated myc-tagged constructs.
