Moreover, HSET's tail domain and its interaction with the E-hook of tubulin are necessary for long-range motility. In vitro polarity-marked bundle assays revealed that HSET selectively generates force in anti-parallel bundles on the order of its stall force. To assess whether the HSET/IFT protein interaction could affect the motor behavior, we then performed fluorescence recovery after photobleaching (FRAP) experiments. To monitor GFP-HSET turnover on mitotic spindle microtubules upon IFT88 depletion, GFP-HSET was introduced in an isogenic manner in the DLD-1 IFT88-AID cell line, described in Fig 1.High School Equivalency Tests (HSET) are designed for adults who do not have their high school diploma.
