Proposed Roots for C. reinhardtii Dynein Genes

Gene Family Root	Root Derivation	Characteristics of Protein Family
DHC	Dynein Heavy Chain	ATPases / Motors
DIC	Dynein Intermediate Chain	WD-repeat proteins
DLI	Dynein Light Intermediate chain	Originally named based on migration between ICs and LCs. Class found only in “cytoplasmic” dyneins, including IFT dynein
DLU	Dynein components with LeUcine-rich repeats	Contain ββα barrels derived from leucine-rich repeats
DLX	Dynein Light chain thioredoXin	Redox-sensitive thioredoxins with vicinal dithiols
DLT	Dynein Light chain Tctex1-like	Tctex1/Tctex2 family proteins; some are also found in conventional cytoplasmic dynein
DLR	Dynein Light chain Roadblock-like	Related to the Roadblock light chains found in conventional cytoplasmic dynein
DLL	Dynein Light chain in LC8 family	Very highly conserved family of dimeric light chains found in many enzyme systems
DLE	Dynein Light chain in EF-hand family	Ca2+-binding components containing EF-hand motif(s)
DCC	Dynein Coiled Coil	Contain extensive regions of coiled -coil structure
DOI	Dynein Outer arm-Interacting	Associate with outer arm dynein but do not fall into other categories
DII	Dynein Inner arm-Interacting	Associate with inner arm dyneins but do not fall into other categories
DAP	Dynein Assembly PIH domain	Required for dynein assembly and contain PIH domains
DAW	Dynein Assembly WD repeat	Required for dynein assembly and contain WD-repeat motifs
DAU	Dynein Assembly leUcine-rich repeat	Required for dynein assembly and contain leucine-rich repeat motifs
DAB	Dynein Assembly Blocked	Required for dynein assembly but do not fall into other categories
