“…The novel feature of KRP85/95 is the ability of its two kinesinlike subunits to heterodimerize, possibly through their coiled-coil stalk domains (121). This may be a general principle, since related KLPs have been identified in mouse (66,122,123), Drosophila (124), Chlamydomonas (125), and Caenorhabditis (44,124), suggesting that these KLPs are members of a new kinesin family (4, 84). Therefore, the potential for KLPs to form different types of oligomers is another mechanism that may be used to generate variation in motor output, and it stresses the importance of identifying and characterizing native motor protein complexes (126).…”
