Protein Spindly (SPDL1)

Required for the localization of dynein and dynactin to the mitotic kintochore. Dynein is thought to control the initial lateral interaction between the kinetochore and spindle microtubules and to facilitate the subsequent creation of end-on kinetochore-microtubule attachments evidenced by the NDC80 complex.

Also required for proper spindle orientation. Does not seem to be required for the removal of spindle assembly checkpoint (SAC) proteins from the kinetochore upon bipolar spindle attachment (PubMed:17576797, PubMed:19468067).
