Dynein light chain type 1 signature


Dynein is a multisubunit microtubule-dependent motor enzyme that acts as the force generating protein of eukaryotic cilia and flagella. The cytoplasmic isoform of dynein acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. Dynein is composed of a number of ATP-binding large subunits, intermediate size subunits and small subunits.

Among the small subunits, there is a family [1,2] of highly conserved proteins which consist of:

  - Chlamydomonas reinhardtii flagellar outer arm dynein 8 Kd and 11 Kd  light
  - Higher eukaryotes cytoplasmic dynein light chain 1.
  - Yeast cytoplasmic dynein light chain 1 (gene DYN2 or SLC1).
  - Caenorhabditis elegans hypothetical dynein light chains M18.2 and T26A5.9.

These proteins are have from 89 to 120 amino acids. As a signature pattern, we selected a highly conserved region.
