Disease relevance of DYNLL1


High impact information on DYNLL1

  • We screened an expression library for proteins that bind the PTH mRNA 3'-UTR, and the sequence of 1 clone was identical to that of the dynein light chain LC8, a component of the dynein complexes that translocate cytoplasmic components along microtubules [2].

Chemical compound and disease context of DYNLL1


Biological context of DYNLL1

  • The LC8-binding domain was mapped to a short peptide segment immediately N-terminal to the kinetochore localization region of 53BP1 [4].
  • We have performed a fine mapping of the 8 kDa dynein light chain (LC8) binding sites throughout the development of a library of consecutive synthetic dodecapeptides covering the amino acid sequences of the various proteins known to interact with this dynein member according to the yeast two hybrid system [5].
  • The structure provides key insights into dimerization of and peptide binding by the multifunctional PIN/LC8 protein [6].
  • The N-terminal domain of the intermediate chain, IC1-289, contains the binding sites for the light chains, and is a highly disordered monomer but gains helical structure upon binding to light chains LC8 and Tctex-1 [7].

Anatomical context of DYNLL1

  • Interestingly, we found that LC8a co-localizes with TRPS1 in dot-like structures in the cell nucleus [8].
  • The cytoskeletal organization and dynamics of this syncytium are poorly understood, but predominant motor components are the LC8 class of cytoplasmic dynein light chains (DLC) [9].

Associations of DYNLL1 with chemical compounds

  • Yeast two-hybrid analysis has revealed that in brain, LC8 associates directly with several proteins such as neuronal nitric oxide synthase, guanylate kinase domain-associated protein and gephyrin [10].

Physical interactions of DYNLL1

  • The LC8-binding domain is completely separated from the p53-binding domain in 53BP1 [4].
