WebMay 1, 2001 · The dynein heavy chain family of isoforms is divided into four functional classes: (i) axonemal (ciliary or flagellar) outer arm dyneins; (ii) axonemal inner arm dyneins; (iii) non-axonemal (‘cytoplasmic’) dynein-1, also called MAP1C, Dhc1a and Dyh1; and (iv) cytoplasmic dynein-2, also called Dhc1b and Dyh2 , . WebMar 17, 2015 · Dynein arms contain varying numbers of heavy (responsible for motor activity), intermediate and light chains [12-15]. Radial spokes and central pair projections are also present in most motile cilia and are further structures known to regulate dynein function .
